Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33666, here are decompositions:
- 19 + 33647 = 33666
- 29 + 33637 = 33666
- 37 + 33629 = 33666
- 43 + 33623 = 33666
- 47 + 33619 = 33666
- 53 + 33613 = 33666
- 67 + 33599 = 33666
- 79 + 33587 = 33666
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.
