Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45146, here are decompositions:
- 7 + 45139 = 45146
- 19 + 45127 = 45146
- 139 + 45007 = 45146
- 163 + 44983 = 45146
- 193 + 44953 = 45146
- 229 + 44917 = 45146
- 307 + 44839 = 45146
- 337 + 44809 = 45146
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.
