Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66662, here are decompositions:
- 19 + 66643 = 66662
- 61 + 66601 = 66662
- 109 + 66553 = 66662
- 139 + 66523 = 66662
- 163 + 66499 = 66662
- 199 + 66463 = 66662
- 733 + 65929 = 66662
- 811 + 65851 = 66662
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.
