Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523624, here are decompositions:

103 + 31523521 = 31523624
151 + 31523473 = 31523624
157 + 31523467 = 31523624
163 + 31523461 = 31523624
277 + 31523347 = 31523624
331 + 31523293 = 31523624
373 + 31523251 = 31523624
397 + 31523227 = 31523624

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.3.40.

Address: 1.225.3.40
Class: public
IPv4-mapped IPv6: ::ffff:1.225.3.40

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.
