Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605388, here are decompositions:

79 + 33605309 = 33605388
97 + 33605291 = 33605388
137 + 33605251 = 33605388
181 + 33605207 = 33605388
191 + 33605197 = 33605388
211 + 33605177 = 33605388
239 + 33605149 = 33605388
251 + 33605137 = 33605388

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.199.12.

Address: 2.0.199.12
Class: public
IPv4-mapped IPv6: ::ffff:2.0.199.12

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