Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530264, here are decompositions:

53 + 31530211 = 31530264
61 + 31530203 = 31530264
67 + 31530197 = 31530264
83 + 31530181 = 31530264
167 + 31530097 = 31530264
263 + 31530001 = 31530264
331 + 31529933 = 31530264
373 + 31529891 = 31530264

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.
