Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488816, here are decompositions:

23 + 2147488793 = 2147488816
89 + 2147488727 = 2147488816
173 + 2147488643 = 2147488816
197 + 2147488619 = 2147488816
257 + 2147488559 = 2147488816
509 + 2147488307 = 2147488816
569 + 2147488247 = 2147488816
653 + 2147488163 = 2147488816

Showing the first eight; more decompositions exist.
