Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525156, here are decompositions:

29 + 31525127 = 31525156
53 + 31525103 = 31525156
149 + 31525007 = 31525156
167 + 31524989 = 31525156
263 + 31524893 = 31525156
293 + 31524863 = 31525156
317 + 31524839 = 31525156
347 + 31524809 = 31525156

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.9.36.

Address: 1.225.9.36
Class: public
IPv4-mapped IPv6: ::ffff:1.225.9.36

Public, routable address (assignable to a host on the internet).

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
