Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136, here are decompositions:
- 5 + 131 = 136
- 23 + 113 = 136
- 29 + 107 = 136
- 47 + 89 = 136
- 53 + 83 = 136

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.
