Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63966, here are decompositions:
- 17 + 63949 = 63966
- 37 + 63929 = 63966
- 53 + 63913 = 63966
- 59 + 63907 = 63966
- 103 + 63863 = 63966
- 109 + 63857 = 63966
- 113 + 63853 = 63966
- 127 + 63839 = 63966
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.
