Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535706, here are decompositions:

67 + 31535639 = 31535706
73 + 31535633 = 31535706
113 + 31535593 = 31535706
157 + 31535549 = 31535706
239 + 31535467 = 31535706
277 + 31535429 = 31535706
283 + 31535423 = 31535706
379 + 31535327 = 31535706

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.
