Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509802, here are decompositions:

5 + 509797 = 509802
19 + 509783 = 509802
61 + 509741 = 509802
71 + 509731 = 509802
79 + 509723 = 509802
103 + 509699 = 509802
109 + 509693 = 509802
113 + 509689 = 509802

Showing the first eight; more decompositions exist.
