Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491488, here are decompositions:

11 + 2147491477 = 2147491488
71 + 2147491417 = 2147491488
127 + 2147491361 = 2147491488
139 + 2147491349 = 2147491488
211 + 2147491277 = 2147491488
227 + 2147491261 = 2147491488
239 + 2147491249 = 2147491488
251 + 2147491237 = 2147491488

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.30.160.

Address: 128.0.30.160
Class: public
IPv4-mapped IPv6: ::ffff:128.0.30.160
