Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509730, here are decompositions:

7 + 509723 = 509730
31 + 509699 = 509730
37 + 509693 = 509730
41 + 509689 = 509730
43 + 509687 = 509730
71 + 509659 = 509730
83 + 509647 = 509730
97 + 509633 = 509730

Showing the first eight; more decompositions exist.
