Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489918, here are decompositions:

19 + 2147489899 = 2147489918
97 + 2147489821 = 2147489918
331 + 2147489587 = 2147489918
571 + 2147489347 = 2147489918
619 + 2147489299 = 2147489918
829 + 2147489089 = 2147489918
859 + 2147489059 = 2147489918
1051 + 2147488867 = 2147489918

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.126.
