Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33552172, here are decompositions:

11 + 33552161 = 33552172
23 + 33552149 = 33552172
41 + 33552131 = 33552172
83 + 33552089 = 33552172
149 + 33552023 = 33552172
179 + 33551993 = 33552172
263 + 33551909 = 33552172
389 + 33551783 = 33552172

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.247.44.

Address: 1.255.247.44
Class: public
IPv4-mapped IPv6: ::ffff:1.255.247.44

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