Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484542, here are decompositions:

43 + 2147484499 = 2147484542
103 + 2147484439 = 2147484542
109 + 2147484433 = 2147484542
193 + 2147484349 = 2147484542
211 + 2147484331 = 2147484542
271 + 2147484271 = 2147484542
283 + 2147484259 = 2147484542
433 + 2147484109 = 2147484542

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.3.126.
