Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484688, here are decompositions:

47 + 2147484641 = 2147484688
71 + 2147484617 = 2147484688
197 + 2147484491 = 2147484688
227 + 2147484461 = 2147484688
311 + 2147484377 = 2147484688
449 + 2147484239 = 2147484688
467 + 2147484221 = 2147484688
491 + 2147484197 = 2147484688

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.4.16.

Address: 128.0.4.16
Class: public
IPv4-mapped IPv6: ::ffff:128.0.4.16

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