Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43740, here are decompositions:
- 19 + 43721 = 43740
- 23 + 43717 = 43740
- 29 + 43711 = 43740
- 71 + 43669 = 43740
- 79 + 43661 = 43740
- 89 + 43651 = 43740
- 107 + 43633 = 43740
- 113 + 43627 = 43740
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.
