Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484858, here are decompositions:

7 + 2147484851 = 2147484858
37 + 2147484821 = 2147484858
67 + 2147484791 = 2147484858
107 + 2147484751 = 2147484858
137 + 2147484721 = 2147484858
179 + 2147484679 = 2147484858
241 + 2147484617 = 2147484858
257 + 2147484601 = 2147484858

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.4.186.
