Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509798, here are decompositions:

31 + 509767 = 509798
61 + 509737 = 509798
67 + 509731 = 509798
109 + 509689 = 509798
139 + 509659 = 509798
151 + 509647 = 509798
229 + 509569 = 509798
241 + 509557 = 509798

Showing the first eight; more decompositions exist.
