Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483856, here are decompositions:

43 + 2147483813 = 2147483856
73 + 2147483783 = 2147483856
79 + 2147483777 = 2147483856
113 + 2147483743 = 2147483856
163 + 2147483693 = 2147483856
197 + 2147483659 = 2147483856
227 + 2147483629 = 2147483856
269 + 2147483587 = 2147483856

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.208.
