Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606442, here are decompositions:

29 + 33606413 = 33606442
41 + 33606401 = 33606442
71 + 33606371 = 33606442
239 + 33606203 = 33606442
251 + 33606191 = 33606442
263 + 33606179 = 33606442
269 + 33606173 = 33606442
293 + 33606149 = 33606442

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.203.42.

Address: 2.0.203.42
Class: public
IPv4-mapped IPv6: ::ffff:2.0.203.42

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