Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31422, here are decompositions:
- 29 + 31393 = 31422
- 31 + 31391 = 31422
- 43 + 31379 = 31422
- 89 + 31333 = 31422
- 101 + 31321 = 31422
- 103 + 31319 = 31422
- 151 + 31271 = 31422
- 163 + 31259 = 31422
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.
