Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483790, here are decompositions:

7 + 2147483783 = 2147483790
13 + 2147483777 = 2147483790
47 + 2147483743 = 2147483790
97 + 2147483693 = 2147483790
131 + 2147483659 = 2147483790
211 + 2147483579 = 2147483790
227 + 2147483563 = 2147483790
241 + 2147483549 = 2147483790

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.142.
