Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491848, here are decompositions:

11 + 2147491837 = 2147491848
17 + 2147491831 = 2147491848
67 + 2147491781 = 2147491848
149 + 2147491699 = 2147491848
157 + 2147491691 = 2147491848
239 + 2147491609 = 2147491848
241 + 2147491607 = 2147491848
251 + 2147491597 = 2147491848

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.32.8.
