Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556440, here are decompositions:

11 + 33556429 = 33556440
17 + 33556423 = 33556440
37 + 33556403 = 33556440
41 + 33556399 = 33556440
59 + 33556381 = 33556440
79 + 33556361 = 33556440
83 + 33556357 = 33556440
97 + 33556343 = 33556440

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.7.216.

Address: 2.0.7.216
Class: public
IPv4-mapped IPv6: ::ffff:2.0.7.216

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