Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542362, here are decompositions:

3 + 31542359 = 31542362
199 + 31542163 = 31542362
331 + 31542031 = 31542362
349 + 31542013 = 31542362
373 + 31541989 = 31542362
463 + 31541899 = 31542362
601 + 31541761 = 31542362
751 + 31541611 = 31542362

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.76.90.

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.
