Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531674, here are decompositions:

7 + 31531667 = 31531674
47 + 31531627 = 31531674
151 + 31531523 = 31531674
191 + 31531483 = 31531674
257 + 31531417 = 31531674
271 + 31531403 = 31531674
373 + 31531301 = 31531674
401 + 31531273 = 31531674

Showing the first eight; more decompositions exist.

Federal Reserve district 3 (Philadelphia)

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
