Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489824, here are decompositions:

3 + 2147489821 = 2147489824
5 + 2147489819 = 2147489824
107 + 2147489717 = 2147489824
173 + 2147489651 = 2147489824
281 + 2147489543 = 2147489824
383 + 2147489441 = 2147489824
401 + 2147489423 = 2147489824
617 + 2147489207 = 2147489824

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.32.
