Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484838, here are decompositions:

17 + 2147484821 = 2147484838
47 + 2147484791 = 2147484838
197 + 2147484641 = 2147484838
227 + 2147484611 = 2147484838
269 + 2147484569 = 2147484838
311 + 2147484527 = 2147484838
347 + 2147484491 = 2147484838
461 + 2147484377 = 2147484838

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.4.166.
