Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460732, here are decompositions:

3 + 31460729 = 31460732
31 + 31460701 = 31460732
151 + 31460581 = 31460732
181 + 31460551 = 31460732
223 + 31460509 = 31460732
241 + 31460491 = 31460732
439 + 31460293 = 31460732
733 + 31459999 = 31460732

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.13.124.

Address: 1.224.13.124
Class: public
IPv4-mapped IPv6: ::ffff:1.224.13.124

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