Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11662, here are decompositions:
- 5 + 11657 = 11662
- 29 + 11633 = 11662
- 41 + 11621 = 11662
- 83 + 11579 = 11662
- 113 + 11549 = 11662
- 173 + 11489 = 11662
- 179 + 11483 = 11662
- 191 + 11471 = 11662
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.
