Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485066, here are decompositions:

137 + 2147484929 = 2147485066
197 + 2147484869 = 2147485066
449 + 2147484617 = 2147485066
827 + 2147484239 = 2147485066
863 + 2147484203 = 2147485066
983 + 2147484083 = 2147485066
1283 + 2147483783 = 2147485066
1289 + 2147483777 = 2147485066

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.5.138.
