Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70742, here are decompositions:
- 13 + 70729 = 70742
- 79 + 70663 = 70742
- 103 + 70639 = 70742
- 193 + 70549 = 70742
- 241 + 70501 = 70742
- 283 + 70459 = 70742
- 313 + 70429 = 70742
- 349 + 70393 = 70742
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.
