Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488972, here are decompositions:

53 + 2147488919 = 2147488972
59 + 2147488913 = 2147488972
113 + 2147488859 = 2147488972
179 + 2147488793 = 2147488972
281 + 2147488691 = 2147488972
353 + 2147488619 = 2147488972
359 + 2147488613 = 2147488972
809 + 2147488163 = 2147488972

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.20.204.
