Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474948, here are decompositions:

17 + 31474931 = 31474948
227 + 31474721 = 31474948
257 + 31474691 = 31474948
347 + 31474601 = 31474948
389 + 31474559 = 31474948
467 + 31474481 = 31474948
641 + 31474307 = 31474948
647 + 31474301 = 31474948

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.69.4.

Address: 1.224.69.4
Class: public
IPv4-mapped IPv6: ::ffff:1.224.69.4

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