Any/no attempts from your side?

Your sample files aren't too easy, and I guess they're not representative. Anyhow, try
Code:
awk '
NR==1 || !NF    {next}
NR==2           {print "Number1 Number2"
                 next
                }
                {sum[$4]+=$3}
END             {for (s in sum) print s, sum[s]}
' /tmp/example\ 1.txt 
Number1 Number2
99334523 35
97637083 57
99310914 13
92317170 54

NAME

       sum - calculate a sum(1) compatible checksum

SYNOPSIS

       package require Tcl 8.2

       package require sum ?1.0?

       ::crc::sum ?-format format? message

       ::crc::sum ?-format format? -filename file

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 ?-format format? message

       ::crc::sum ?-format format? -filename file
	      The command takes string data or a file name and returns a checksum value calculated using the sum(1) algorithm. The result is  for-
	      matted using the format(n) specifier provided or as an unsigned integer (%u) by default.

OPTIONS

       -filename name
	      Return a checksum for the file contents instead of for parameter data.

       -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
