Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64648, here are decompositions:
- 47 + 64601 = 64648
- 71 + 64577 = 64648
- 149 + 64499 = 64648
- 197 + 64451 = 64648
- 347 + 64301 = 64648
- 431 + 64217 = 64648
- 461 + 64187 = 64648
- 491 + 64157 = 64648
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.
