Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467272, here are decompositions:

13 + 31467259 = 31467272
43 + 31467229 = 31467272
73 + 31467199 = 31467272
103 + 31467169 = 31467272
139 + 31467133 = 31467272
283 + 31466989 = 31467272
373 + 31466899 = 31467272
379 + 31466893 = 31467272

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.39.8.

Address: 1.224.39.8
Class: public
IPv4-mapped IPv6: ::ffff:1.224.39.8

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