Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533326, here are decompositions:

67 + 31533259 = 31533326
193 + 31533133 = 31533326
199 + 31533127 = 31533326
229 + 31533097 = 31533326
313 + 31533013 = 31533326
367 + 31532959 = 31533326
463 + 31532863 = 31533326
577 + 31532749 = 31533326

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.
