Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487028, here are decompositions:

47 + 2147486981 = 2147487028
59 + 2147486969 = 2147487028
101 + 2147486927 = 2147487028
149 + 2147486879 = 2147487028
179 + 2147486849 = 2147487028
317 + 2147486711 = 2147487028
359 + 2147486669 = 2147487028
521 + 2147486507 = 2147487028

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.52.
