Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78388, here are decompositions:
- 41 + 78347 = 78388
- 47 + 78341 = 78388
- 71 + 78317 = 78388
- 197 + 78191 = 78388
- 251 + 78137 = 78388
- 347 + 78041 = 78388
- 389 + 77999 = 78388
- 419 + 77969 = 78388
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.
