Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509732, here are decompositions:

43 + 509689 = 509732
73 + 509659 = 509732
79 + 509653 = 509732
109 + 509623 = 509732
151 + 509581 = 509732
163 + 509569 = 509732
211 + 509521 = 509732
283 + 509449 = 509732

Showing the first eight; more decompositions exist.
