Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536996, here are decompositions:

5 + 31536991 = 31536996
13 + 31536983 = 31536996
37 + 31536959 = 31536996
53 + 31536943 = 31536996
59 + 31536937 = 31536996
79 + 31536917 = 31536996
149 + 31536847 = 31536996
167 + 31536829 = 31536996

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.
