Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543086, here are decompositions:

7 + 31543079 = 31543086
17 + 31543069 = 31543086
19 + 31543067 = 31543086
67 + 31543019 = 31543086
137 + 31542949 = 31543086
149 + 31542937 = 31543086
229 + 31542857 = 31543086
257 + 31542829 = 31543086

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.
