Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487868, here are decompositions:

41 + 2147487827 = 2147487868
89 + 2147487779 = 2147487868
167 + 2147487701 = 2147487868
179 + 2147487689 = 2147487868
257 + 2147487611 = 2147487868
269 + 2147487599 = 2147487868
359 + 2147487509 = 2147487868
419 + 2147487449 = 2147487868

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.16.124.
