Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71178, here are decompositions:
- 7 + 71171 = 71178
- 11 + 71167 = 71178
- 17 + 71161 = 71178
- 31 + 71147 = 71178
- 59 + 71119 = 71178
- 89 + 71089 = 71178
- 97 + 71081 = 71178
- 109 + 71069 = 71178
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.
