Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489728, here are decompositions:

11 + 2147489717 = 2147489728
29 + 2147489699 = 2147489728
89 + 2147489639 = 2147489728
149 + 2147489579 = 2147489728
191 + 2147489537 = 2147489728
431 + 2147489297 = 2147489728
521 + 2147489207 = 2147489728
641 + 2147489087 = 2147489728

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.192.
