Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500802, here are decompositions:

79 + 2147500723 = 2147500802
211 + 2147500591 = 2147500802
241 + 2147500561 = 2147500802
463 + 2147500339 = 2147500802
619 + 2147500183 = 2147500802
691 + 2147500111 = 2147500802
709 + 2147500093 = 2147500802
739 + 2147500063 = 2147500802

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.67.2.
