Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40646, here are decompositions:
- 7 + 40639 = 40646
- 19 + 40627 = 40646
- 37 + 40609 = 40646
- 103 + 40543 = 40646
- 127 + 40519 = 40646
- 139 + 40507 = 40646
- 163 + 40483 = 40646
- 223 + 40423 = 40646
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.
