Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529738, here are decompositions:

61 + 31529677 = 31529738
67 + 31529671 = 31529738
109 + 31529629 = 31529738
181 + 31529557 = 31529738
199 + 31529539 = 31529738
307 + 31529431 = 31529738
379 + 31529359 = 31529738
571 + 31529167 = 31529738

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.
