Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3146, here are decompositions:
- 37 + 3109 = 3146
- 67 + 3079 = 3146
- 79 + 3067 = 3146
- 97 + 3049 = 3146
- 109 + 3037 = 3146
- 127 + 3019 = 3146
- 193 + 2953 = 3146
- 229 + 2917 = 3146
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.
