Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484556, here are decompositions:

3 + 2147484553 = 2147484556
29 + 2147484527 = 2147484556
179 + 2147484377 = 2147484556
317 + 2147484239 = 2147484556
353 + 2147484203 = 2147484556
359 + 2147484197 = 2147484556
389 + 2147484167 = 2147484556
557 + 2147483999 = 2147484556

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.3.140.
