Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484380, here are decompositions:

3 + 2147484377 = 2147484380
31 + 2147484349 = 2147484380
43 + 2147484337 = 2147484380
103 + 2147484277 = 2147484380
109 + 2147484271 = 2147484380
157 + 2147484223 = 2147484380
271 + 2147484109 = 2147484380
337 + 2147484043 = 2147484380

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.2.220.
