Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13084, here are decompositions:
- 41 + 13043 = 13084
- 47 + 13037 = 13084
- 83 + 13001 = 13084
- 101 + 12983 = 13084
- 131 + 12953 = 13084
- 167 + 12917 = 13084
- 173 + 12911 = 13084
- 191 + 12893 = 13084
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.
