Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501866, here are decompositions:

89 + 2147501777 = 2147501866
149 + 2147501717 = 2147501866
197 + 2147501669 = 2147501866
239 + 2147501627 = 2147501866
347 + 2147501519 = 2147501866
563 + 2147501303 = 2147501866
593 + 2147501273 = 2147501866
617 + 2147501249 = 2147501866

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.71.42.
