Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43902, here are decompositions:
- 11 + 43891 = 43902
- 13 + 43889 = 43902
- 101 + 43801 = 43902
- 109 + 43793 = 43902
- 113 + 43789 = 43902
- 149 + 43753 = 43902
- 181 + 43721 = 43902
- 191 + 43711 = 43902
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.
