Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521404, here are decompositions:

3 + 33521401 = 33521404
11 + 33521393 = 33521404
83 + 33521321 = 33521404
167 + 33521237 = 33521404
227 + 33521177 = 33521404
233 + 33521171 = 33521404
263 + 33521141 = 33521404
317 + 33521087 = 33521404

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.126.252.

Address: 1.255.126.252
Class: public
IPv4-mapped IPv6: ::ffff:1.255.126.252

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