Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488930, here are decompositions:

11 + 2147488919 = 2147488930
17 + 2147488913 = 2147488930
23 + 2147488907 = 2147488930
71 + 2147488859 = 2147488930
137 + 2147488793 = 2147488930
179 + 2147488751 = 2147488930
239 + 2147488691 = 2147488930
311 + 2147488619 = 2147488930

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.20.162.

Address: 128.0.20.162
