Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45722, here are decompositions:
- 31 + 45691 = 45722
- 109 + 45613 = 45722
- 181 + 45541 = 45722
- 199 + 45523 = 45722
- 241 + 45481 = 45722
- 283 + 45439 = 45722
- 379 + 45343 = 45722
- 433 + 45289 = 45722
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.
