Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617680, here are decompositions:

59 + 33617621 = 33617680
137 + 33617543 = 33617680
149 + 33617531 = 33617680
191 + 33617489 = 33617680
233 + 33617447 = 33617680
269 + 33617411 = 33617680
347 + 33617333 = 33617680
359 + 33617321 = 33617680

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.247.16.

Address: 2.0.247.16
Class: public
IPv4-mapped IPv6: ::ffff:2.0.247.16

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