Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98818, here are decompositions:
- 11 + 98807 = 98818
- 17 + 98801 = 98818
- 89 + 98729 = 98818
- 101 + 98717 = 98818
- 107 + 98711 = 98818
- 149 + 98669 = 98818
- 179 + 98639 = 98818
- 191 + 98627 = 98818
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.
