Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509746, here are decompositions:

5 + 509741 = 509746
23 + 509723 = 509746
47 + 509699 = 509746
53 + 509693 = 509746
59 + 509687 = 509746
113 + 509633 = 509746
173 + 509573 = 509746
197 + 509549 = 509746

Showing the first eight; more decompositions exist.
