Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25988, here are decompositions:
- 7 + 25981 = 25988
- 19 + 25969 = 25988
- 37 + 25951 = 25988
- 139 + 25849 = 25988
- 229 + 25759 = 25988
- 241 + 25747 = 25988
- 271 + 25717 = 25988
- 331 + 25657 = 25988
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.
