Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509650, here are decompositions:

3 + 509647 = 509650
17 + 509633 = 509650
47 + 509603 = 509650
59 + 509591 = 509650
101 + 509549 = 509650
107 + 509543 = 509650
137 + 509513 = 509650
173 + 509477 = 509650

Showing the first eight; more decompositions exist.
