Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621200, here are decompositions:

31 + 33621169 = 33621200
37 + 33621163 = 33621200
163 + 33621037 = 33621200
241 + 33620959 = 33621200
271 + 33620929 = 33621200
397 + 33620803 = 33621200
433 + 33620767 = 33621200
439 + 33620761 = 33621200

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.4.208.

Address: 2.1.4.208
Class: public
IPv4-mapped IPv6: ::ffff:2.1.4.208

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