Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486876, here are decompositions:

19 + 2147486857 = 2147486876
127 + 2147486749 = 2147486876
277 + 2147486599 = 2147486876
349 + 2147486527 = 2147486876
463 + 2147486413 = 2147486876
547 + 2147486329 = 2147486876
607 + 2147486269 = 2147486876
673 + 2147486203 = 2147486876

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.12.156.

Address: 128.0.12.156
Class: public
IPv4-mapped IPv6: ::ffff:128.0.12.156
