Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585660, here are decompositions:

13 + 33585647 = 33585660
19 + 33585641 = 33585660
23 + 33585637 = 33585660
41 + 33585619 = 33585660
47 + 33585613 = 33585660
61 + 33585599 = 33585660
67 + 33585593 = 33585660
79 + 33585581 = 33585660

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.121.252.

Address: 2.0.121.252
Class: public
IPv4-mapped IPv6: ::ffff:2.0.121.252

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