Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486756, here are decompositions:

7 + 2147486749 = 2147486756
67 + 2147486689 = 2147486756
139 + 2147486617 = 2147486756
157 + 2147486599 = 2147486756
199 + 2147486557 = 2147486756
229 + 2147486527 = 2147486756
439 + 2147486317 = 2147486756
463 + 2147486293 = 2147486756

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.12.36.
