Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488810, here are decompositions:

17 + 2147488793 = 2147488810
59 + 2147488751 = 2147488810
83 + 2147488727 = 2147488810
167 + 2147488643 = 2147488810
191 + 2147488619 = 2147488810
197 + 2147488613 = 2147488810
251 + 2147488559 = 2147488810
293 + 2147488517 = 2147488810

Showing the first eight; more decompositions exist.
