Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509720, here are decompositions:

31 + 509689 = 509720
61 + 509659 = 509720
67 + 509653 = 509720
73 + 509647 = 509720
97 + 509623 = 509720
139 + 509581 = 509720
151 + 509569 = 509720
157 + 509563 = 509720

Showing the first eight; more decompositions exist.
