Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607304, here are decompositions:

5 + 31607299 = 31607304
7 + 31607297 = 31607304
11 + 31607293 = 31607304
13 + 31607291 = 31607304
23 + 31607281 = 31607304
41 + 31607263 = 31607304
67 + 31607237 = 31607304
97 + 31607207 = 31607304

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.74.8.

Address: 1.226.74.8
Class: public
IPv4-mapped IPv6: ::ffff:1.226.74.8

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