Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80130, here are decompositions:
- 19 + 80111 = 80130
- 23 + 80107 = 80130
- 53 + 80077 = 80130
- 59 + 80071 = 80130
- 79 + 80051 = 80130
- 109 + 80021 = 80130
- 131 + 79999 = 80130
- 151 + 79979 = 80130
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.
