Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16722, here are decompositions:
- 19 + 16703 = 16722
- 23 + 16699 = 16722
- 29 + 16693 = 16722
- 31 + 16691 = 16722
- 61 + 16661 = 16722
- 71 + 16651 = 16722
- 73 + 16649 = 16722
- 89 + 16633 = 16722
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.
