Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463962, here are decompositions:

3 + 31463959 = 31463962
41 + 31463921 = 31463962
53 + 31463909 = 31463962
71 + 31463891 = 31463962
83 + 31463879 = 31463962
113 + 31463849 = 31463962
281 + 31463681 = 31463962
443 + 31463519 = 31463962

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.26.26.

Address: 1.224.26.26
Class: public
IPv4-mapped IPv6: ::ffff:1.224.26.26

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