Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613820, here are decompositions:

3 + 33613817 = 33613820
13 + 33613807 = 33613820
109 + 33613711 = 33613820
139 + 33613681 = 33613820
199 + 33613621 = 33613820
223 + 33613597 = 33613820
271 + 33613549 = 33613820
283 + 33613537 = 33613820

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.231.252.

Address: 2.0.231.252
Class: public
IPv4-mapped IPv6: ::ffff:2.0.231.252

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