Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489308, here are decompositions:

11 + 2147489297 = 2147489308
17 + 2147489291 = 2147489308
101 + 2147489207 = 2147489308
311 + 2147488997 = 2147489308
389 + 2147488919 = 2147489308
401 + 2147488907 = 2147489308
449 + 2147488859 = 2147489308
557 + 2147488751 = 2147489308

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.28.
