Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535146, here are decompositions:

3 + 31535143 = 31535146
23 + 31535123 = 31535146
89 + 31535057 = 31535146
113 + 31535033 = 31535146
233 + 31534913 = 31535146
347 + 31534799 = 31535146
359 + 31534787 = 31535146
389 + 31534757 = 31535146

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.
