Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483972, here are decompositions:

43 + 2147483929 = 2147483972
79 + 2147483893 = 2147483972
103 + 2147483869 = 2147483972
229 + 2147483743 = 2147483972
313 + 2147483659 = 2147483972
409 + 2147483563 = 2147483972
619 + 2147483353 = 2147483972
919 + 2147483053 = 2147483972

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.1.68.
