Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486730, here are decompositions:

19 + 2147486711 = 2147486730
23 + 2147486707 = 2147486730
41 + 2147486689 = 2147486730
61 + 2147486669 = 2147486730
89 + 2147486641 = 2147486730
113 + 2147486617 = 2147486730
131 + 2147486599 = 2147486730
173 + 2147486557 = 2147486730

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.12.10.

Address: 128.0.12.10
