Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77826, here are decompositions:
- 13 + 77813 = 77826
- 29 + 77797 = 77826
- 43 + 77783 = 77826
- 53 + 77773 = 77826
- 79 + 77747 = 77826
- 83 + 77743 = 77826
- 103 + 77723 = 77826
- 107 + 77719 = 77826
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.
