Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490112, here are decompositions:

3 + 2147490109 = 2147490112
23 + 2147490089 = 2147490112
59 + 2147490053 = 2147490112
101 + 2147490011 = 2147490112
239 + 2147489873 = 2147490112
263 + 2147489849 = 2147490112
269 + 2147489843 = 2147490112
293 + 2147489819 = 2147490112

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.25.64.
