Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488758, here are decompositions:

7 + 2147488751 = 2147488758
17 + 2147488741 = 2147488758
31 + 2147488727 = 2147488758
67 + 2147488691 = 2147488758
139 + 2147488619 = 2147488758
179 + 2147488579 = 2147488758
199 + 2147488559 = 2147488758
241 + 2147488517 = 2147488758

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.19.246.
