Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484554, here are decompositions:

13 + 2147484541 = 2147484554
37 + 2147484517 = 2147484554
223 + 2147484331 = 2147484554
277 + 2147484277 = 2147484554
283 + 2147484271 = 2147484554
331 + 2147484223 = 2147484554
547 + 2147484007 = 2147484554
661 + 2147483893 = 2147484554

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.3.138.
