Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489724, here are decompositions:

7 + 2147489717 = 2147489724
11 + 2147489713 = 2147489724
71 + 2147489653 = 2147489724
73 + 2147489651 = 2147489724
137 + 2147489587 = 2147489724
181 + 2147489543 = 2147489724
241 + 2147489483 = 2147489724
251 + 2147489473 = 2147489724

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.188.

Address: 128.0.23.188
