Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78634, here are decompositions:
- 11 + 78623 = 78634
- 41 + 78593 = 78634
- 137 + 78497 = 78634
- 167 + 78467 = 78634
- 197 + 78437 = 78634
- 233 + 78401 = 78634
- 293 + 78341 = 78634
- 317 + 78317 = 78634
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.
