Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99998, here are decompositions:
- 7 + 99991 = 99998
- 37 + 99961 = 99998
- 97 + 99901 = 99998
- 127 + 99871 = 99998
- 139 + 99859 = 99998
- 181 + 99817 = 99998
- 211 + 99787 = 99998
- 277 + 99721 = 99998
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.
