Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78456, here are decompositions:
- 17 + 78439 = 78456
- 19 + 78437 = 78456
- 29 + 78427 = 78456
- 89 + 78367 = 78456
- 109 + 78347 = 78456
- 139 + 78317 = 78456
- 149 + 78307 = 78456
- 173 + 78283 = 78456
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.
