Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539702, here are decompositions:

31 + 31539671 = 31539702
41 + 31539661 = 31539702
43 + 31539659 = 31539702
53 + 31539649 = 31539702
59 + 31539643 = 31539702
109 + 31539593 = 31539702
179 + 31539523 = 31539702
263 + 31539439 = 31539702

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.
