Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31202, here are decompositions:
- 13 + 31189 = 31202
- 19 + 31183 = 31202
- 43 + 31159 = 31202
- 79 + 31123 = 31202
- 139 + 31063 = 31202
- 151 + 31051 = 31202
- 163 + 31039 = 31202
- 271 + 30931 = 31202
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.
