Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509638, here are decompositions:

5 + 509633 = 509638
47 + 509591 = 509638
89 + 509549 = 509638
197 + 509441 = 509638
491 + 509147 = 509638
677 + 508961 = 509638
719 + 508919 = 509638
797 + 508841 = 509638

Showing the first eight; more decompositions exist.
