Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16858, here are decompositions:
- 29 + 16829 = 16858
- 47 + 16811 = 16858
- 71 + 16787 = 16858
- 167 + 16691 = 16858
- 197 + 16661 = 16858
- 227 + 16631 = 16858
- 239 + 16619 = 16858
- 251 + 16607 = 16858
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.
