Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467984, here are decompositions:

17 + 31467967 = 31467984
47 + 31467937 = 31467984
73 + 31467911 = 31467984
131 + 31467853 = 31467984
137 + 31467847 = 31467984
173 + 31467811 = 31467984
257 + 31467727 = 31467984
263 + 31467721 = 31467984

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.41.208.

Address: 1.224.41.208
Class: public
IPv4-mapped IPv6: ::ffff:1.224.41.208

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