Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487238, here are decompositions:

11 + 2147487227 = 2147487238
179 + 2147487059 = 2147487238
257 + 2147486981 = 2147487238
269 + 2147486969 = 2147487238
311 + 2147486927 = 2147487238
359 + 2147486879 = 2147487238
389 + 2147486849 = 2147487238
419 + 2147486819 = 2147487238

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.6.
