Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486772, here are decompositions:

23 + 2147486749 = 2147486772
31 + 2147486741 = 2147486772
61 + 2147486711 = 2147486772
83 + 2147486689 = 2147486772
103 + 2147486669 = 2147486772
131 + 2147486641 = 2147486772
173 + 2147486599 = 2147486772
241 + 2147486531 = 2147486772

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.12.52.
