Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476988, here are decompositions:

29 + 31476959 = 31476988
41 + 31476947 = 31476988
71 + 31476917 = 31476988
107 + 31476881 = 31476988
167 + 31476821 = 31476988
401 + 31476587 = 31476988
479 + 31476509 = 31476988
617 + 31476371 = 31476988

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.76.252.

Address: 1.224.76.252
Class: public
IPv4-mapped IPv6: ::ffff:1.224.76.252

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