Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97220, here are decompositions:
- 7 + 97213 = 97220
- 43 + 97177 = 97220
- 61 + 97159 = 97220
- 103 + 97117 = 97220
- 139 + 97081 = 97220
- 181 + 97039 = 97220
- 199 + 97021 = 97220
- 223 + 96997 = 97220
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.
