Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72834, here are decompositions:
- 11 + 72823 = 72834
- 17 + 72817 = 72834
- 37 + 72797 = 72834
- 67 + 72767 = 72834
- 71 + 72763 = 72834
- 101 + 72733 = 72834
- 107 + 72727 = 72834
- 127 + 72707 = 72834
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.
