Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490428, here are decompositions:

19 + 33490409 = 33490428
31 + 33490397 = 33490428
47 + 33490381 = 33490428
67 + 33490361 = 33490428
107 + 33490321 = 33490428
131 + 33490297 = 33490428
149 + 33490279 = 33490428
157 + 33490271 = 33490428

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.5.252.

Address: 1.255.5.252
Class: public
IPv4-mapped IPv6: ::ffff:1.255.5.252

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