Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484678, here are decompositions:

37 + 2147484641 = 2147484678
61 + 2147484617 = 2147484678
67 + 2147484611 = 2147484678
109 + 2147484569 = 2147484678
137 + 2147484541 = 2147484678
151 + 2147484527 = 2147484678
179 + 2147484499 = 2147484678
239 + 2147484439 = 2147484678

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.4.6.
