Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500918, here are decompositions:

11 + 2147500907 = 2147500918
29 + 2147500889 = 2147500918
47 + 2147500871 = 2147500918
137 + 2147500781 = 2147500918
257 + 2147500661 = 2147500918
359 + 2147500559 = 2147500918
419 + 2147500499 = 2147500918
557 + 2147500361 = 2147500918

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.67.118.
