Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484762, here are decompositions:

11 + 2147484751 = 2147484762
29 + 2147484733 = 2147484762
41 + 2147484721 = 2147484762
83 + 2147484679 = 2147484762
149 + 2147484613 = 2147484762
151 + 2147484611 = 2147484762
193 + 2147484569 = 2147484762
263 + 2147484499 = 2147484762

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.4.90.
