Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487118, here are decompositions:

5 + 2147487113 = 2147487118
41 + 2147487077 = 2147487118
59 + 2147487059 = 2147487118
89 + 2147487029 = 2147487118
137 + 2147486981 = 2147487118
149 + 2147486969 = 2147487118
191 + 2147486927 = 2147487118
239 + 2147486879 = 2147487118

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.142.
