Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532974, here are decompositions:

3 + 31532971 = 31532974
101 + 31532873 = 31532974
107 + 31532867 = 31532974
197 + 31532777 = 31532974
281 + 31532693 = 31532974
401 + 31532573 = 31532974
467 + 31532507 = 31532974
857 + 31532117 = 31532974

Showing the first eight; more decompositions exist.

IPv4 address

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.
