Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486912, here are decompositions:

3 + 2147486909 = 2147486912
61 + 2147486851 = 2147486912
163 + 2147486749 = 2147486912
223 + 2147486689 = 2147486912
271 + 2147486641 = 2147486912
313 + 2147486599 = 2147486912
499 + 2147486413 = 2147486912
601 + 2147486311 = 2147486912

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.12.192.

Address: 128.0.12.192
Class: public
IPv4-mapped IPv6: ::ffff:128.0.12.192

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