Any/no attempts from your side?

Your sample files aren't too easy, and I guess they're not representative. Anyhow, try
awk '
NR==1 || !NF    {next}
NR==2           {print "Number1 Number2"
END             {for (s in sum) print s, sum[s]}
' /tmp/example\ 1.txt 
Number1 Number2
99334523 35
97637083 57
99310914 13
92317170 54

sum - Calculate a sum(1) compatible checksum SYNOPSIS
package require Tcl 8.2 package require sum ?1.1.0? ::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ] _________________________________________________________________ DESCRIPTION
This package provides a Tcl-only implementation of the sum(1) command which calculates a 16 bit checksum value from the input data. The BSD sum algorithm is used by default but the SysV algorithm is also available. COMMANDS
::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ] The command takes string data or a file name or a channel and returns a checksum value calculated using the sum(1) algorithm. The result is formatted using the format(3tcl) specifier provided or as an unsigned integer (%u) by default. OPTIONS
-sysv The SysV algorithm is fairly naive. The byte values are summed and any overflow is discarded. The lowest 16 bits are returned as the checksum. Input with the same content but different ordering will give the same result. -bsd This algorithm is similar to the SysV version but includes a bit rotation step which provides a dependency on the order of the data values. -filename name Return a checksum for the file contents instead of for parameter data. -channel chan Return a checksum for the contents of the specified channel. The channel must be open for reading and should be configured for binary translation. The channel will no be closed on completion. -chunksize size Set the block size used when reading data from either files or channels. This value defaults to 4096. -format string Return the checksum using an alternative format template. EXAMPLES
% crc::sum "Hello, World!" 37287 % crc::sum -format 0x%X "Hello, World!" 0x91A7 % crc::sum -file sum.tcl 13392 AUTHORS
