Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490768, here are decompositions:

29 + 2147490739 = 2147490768
37 + 2147490731 = 2147490768
41 + 2147490727 = 2147490768
79 + 2147490689 = 2147490768
109 + 2147490659 = 2147490768
179 + 2147490589 = 2147490768
191 + 2147490577 = 2147490768
211 + 2147490557 = 2147490768

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.27.208.
