Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536718, here are decompositions:

11 + 31536707 = 31536718
89 + 31536629 = 31536718
167 + 31536551 = 31536718
179 + 31536539 = 31536718
197 + 31536521 = 31536718
359 + 31536359 = 31536718
431 + 31536287 = 31536718
491 + 31536227 = 31536718

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.
