Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49980, here are decompositions:
- 23 + 49957 = 49980
- 37 + 49943 = 49980
- 41 + 49939 = 49980
- 43 + 49937 = 49980
- 53 + 49927 = 49980
- 59 + 49921 = 49980
- 61 + 49919 = 49980
- 89 + 49891 = 49980
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.
