Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620444, here are decompositions:

7 + 33620437 = 33620444
31 + 33620413 = 33620444
73 + 33620371 = 33620444
103 + 33620341 = 33620444
181 + 33620263 = 33620444
223 + 33620221 = 33620444
331 + 33620113 = 33620444
463 + 33619981 = 33620444

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.1.220.

Address: 2.1.1.220
Class: public
IPv4-mapped IPv6: ::ffff:2.1.1.220

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