Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490258, here are decompositions:

19 + 2147490239 = 2147490258
29 + 2147490229 = 2147490258
41 + 2147490217 = 2147490258
97 + 2147490161 = 2147490258
149 + 2147490109 = 2147490258
181 + 2147490077 = 2147490258
197 + 2147490061 = 2147490258
311 + 2147489947 = 2147490258

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.25.210.
