Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470704, here are decompositions:

3 + 31470701 = 31470704
43 + 31470661 = 31470704
157 + 31470547 = 31470704
367 + 31470337 = 31470704
487 + 31470217 = 31470704
607 + 31470097 = 31470704
631 + 31470073 = 31470704
691 + 31470013 = 31470704

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.52.112.

Address: 1.224.52.112
Class: public
IPv4-mapped IPv6: ::ffff:1.224.52.112

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