Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17996, here are decompositions:
- 7 + 17989 = 17996
- 19 + 17977 = 17996
- 37 + 17959 = 17996
- 67 + 17929 = 17996
- 73 + 17923 = 17996
- 157 + 17839 = 17996
- 283 + 17713 = 17996
- 313 + 17683 = 17996
Showing the first eight; more decompositions exist.

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
