Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42916, here are decompositions:
- 17 + 42899 = 42916
- 53 + 42863 = 42916
- 149 + 42767 = 42916
- 173 + 42743 = 42916
- 179 + 42737 = 42916
- 197 + 42719 = 42916
- 227 + 42689 = 42916
- 233 + 42683 = 42916
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.
