Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23618, here are decompositions:
- 19 + 23599 = 23618
- 37 + 23581 = 23618
- 61 + 23557 = 23618
- 79 + 23539 = 23618
- 109 + 23509 = 23618
- 307 + 23311 = 23618
- 349 + 23269 = 23618
- 367 + 23251 = 23618
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.
