Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488798, here are decompositions:

5 + 2147488793 = 2147488798
47 + 2147488751 = 2147488798
71 + 2147488727 = 2147488798
107 + 2147488691 = 2147488798
179 + 2147488619 = 2147488798
239 + 2147488559 = 2147488798
281 + 2147488517 = 2147488798
491 + 2147488307 = 2147488798

Showing the first eight; more decompositions exist.

IPv4 address
