Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584252, here are decompositions:

5 + 31584247 = 31584252
19 + 31584233 = 31584252
41 + 31584211 = 31584252
59 + 31584193 = 31584252
61 + 31584191 = 31584252
79 + 31584173 = 31584252
109 + 31584143 = 31584252
113 + 31584139 = 31584252

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.239.252.

Address: 1.225.239.252
Class: public
IPv4-mapped IPv6: ::ffff:1.225.239.252

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