Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63940, here are decompositions:
- 11 + 63929 = 63940
- 83 + 63857 = 63940
- 101 + 63839 = 63940
- 131 + 63809 = 63940
- 137 + 63803 = 63940
- 167 + 63773 = 63940
- 179 + 63761 = 63940
- 197 + 63743 = 63940
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.
