Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489746, here are decompositions:

29 + 2147489717 = 2147489746
47 + 2147489699 = 2147489746
107 + 2147489639 = 2147489746
167 + 2147489579 = 2147489746
263 + 2147489483 = 2147489746
449 + 2147489297 = 2147489746
503 + 2147489243 = 2147489746
659 + 2147489087 = 2147489746

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.210.
