4294967295 is obviously 0xffffffff in hexadecimal and -1 if
seen as a signed value what is commonly used in C as a
return value to indicate an error.

"adduser" is a shell script. I had a look at it but I don't
know how you managed to generate that number. The script
calls "pw", that is written in C and probably cannot
increment the maximum 32-bit value.

Untested: You should be save by editing /etc/groups and change
the value by hand. Then call "vipw" to edit /etc/passwd.
After that you need to find files on disk with the wrong
group id. You can do something like
# find /home /var -group 4294967295 -exec ls -l '{}' \;
# find /home /var -group 4294967295 -exec chgrp 1004 '{}' \;
Did I forget anything?
Good luck!
