Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17776, here are decompositions:
- 29 + 17747 = 17776
- 47 + 17729 = 17776
- 107 + 17669 = 17776
- 149 + 17627 = 17776
- 167 + 17609 = 17776
- 179 + 17597 = 17776
- 197 + 17579 = 17776
- 257 + 17519 = 17776
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.
