Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487488, here are decompositions:

37 + 2147487451 = 2147487488
79 + 2147487409 = 2147487488
229 + 2147487259 = 2147487488
241 + 2147487247 = 2147487488
331 + 2147487157 = 2147487488
439 + 2147487049 = 2147487488
631 + 2147486857 = 2147487488
661 + 2147486827 = 2147487488

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.15.0.
