Increment with awk - how to define start value

Hello,
I am running under ubuntu18.04
My question is about awk.
inputfile
Code:
0wo010011oasasds sdjhsdjh=, u12812888
8jsjkahsjajnsanakn akjskjskj=, suhuhuhwx
kskkxmsnnxsnjxsnjxsnjjnjjdi=, 22878ssssss

Below code adds consecutive numbers when string = is found
run_code:
Code:
awk -F'=' -v OFS='=' 'NF == 2 {$2 = ++count $2} 1' inputfile

It gives:
Code:
0wo010011oasasds sdjhsdjh=1, u12812888
8jsjkahsjajnsanakn akjskjskj=2, suhuhuhwx
kskkxmsnnxsnjxsnjxsnjjnjjdi=3, 22878ssssss

What I'd like to do is to start from a defined nr.
Code:
./run_code 500

How would I get below output?
Code:
0wo010011oasasds sdjhsdjh=500, u12812888
8jsjkahsjajnsanakn akjskjskj=501, suhuhuhwx
kskkxmsnnxsnjxsnjxsnjjnjjdi=502, 22878ssssss

Thank you
Boris

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
