Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488018, here are decompositions:

17 + 2147488001 = 2147488018
149 + 2147487869 = 2147488018
191 + 2147487827 = 2147488018
239 + 2147487779 = 2147488018
317 + 2147487701 = 2147488018
419 + 2147487599 = 2147488018
509 + 2147487509 = 2147488018
569 + 2147487449 = 2147488018

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.17.18.
