Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489466, here are decompositions:

29 + 2147489437 = 2147489466
43 + 2147489423 = 2147489466
167 + 2147489299 = 2147489466
223 + 2147489243 = 2147489466
263 + 2147489203 = 2147489466
379 + 2147489087 = 2147489466
383 + 2147489083 = 2147489466
389 + 2147489077 = 2147489466

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.186.

Address: 128.0.22.186
