Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77884, here are decompositions:
- 17 + 77867 = 77884
- 71 + 77813 = 77884
- 83 + 77801 = 77884
- 101 + 77783 = 77884
- 137 + 77747 = 77884
- 173 + 77711 = 77884
- 197 + 77687 = 77884
- 263 + 77621 = 77884
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.
