Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13356, here are decompositions:
- 17 + 13339 = 13356
- 19 + 13337 = 13356
- 29 + 13327 = 13356
- 43 + 13313 = 13356
- 47 + 13309 = 13356
- 59 + 13297 = 13356
- 89 + 13267 = 13356
- 97 + 13259 = 13356
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.
