Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64444, here are decompositions:
- 5 + 64439 = 64444
- 11 + 64433 = 64444
- 41 + 64403 = 64444
- 71 + 64373 = 64444
- 173 + 64271 = 64444
- 227 + 64217 = 64444
- 257 + 64187 = 64444
- 293 + 64151 = 64444
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.
