Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489470, here are decompositions:

29 + 2147489441 = 2147489470
47 + 2147489423 = 2147489470
173 + 2147489297 = 2147489470
179 + 2147489291 = 2147489470
227 + 2147489243 = 2147489470
263 + 2147489207 = 2147489470
383 + 2147489087 = 2147489470
557 + 2147488913 = 2147489470

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.190.

Address: 128.0.22.190
