Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67690, here are decompositions:
- 11 + 67679 = 67690
- 59 + 67631 = 67690
- 71 + 67619 = 67690
- 83 + 67607 = 67690
- 89 + 67601 = 67690
- 101 + 67589 = 67690
- 113 + 67577 = 67690
- 131 + 67559 = 67690
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.
