Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10126, here are decompositions:
- 23 + 10103 = 10126
- 47 + 10079 = 10126
- 59 + 10067 = 10126
- 89 + 10037 = 10126
- 197 + 9929 = 10126
- 239 + 9887 = 10126
- 269 + 9857 = 10126
- 293 + 9833 = 10126
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.
