Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509806, here are decompositions:

5 + 509801 = 509806
23 + 509783 = 509806
83 + 509723 = 509806
107 + 509699 = 509806
113 + 509693 = 509806
173 + 509633 = 509806
233 + 509573 = 509806
257 + 509549 = 509806

Showing the first eight; more decompositions exist.
