Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509828, here are decompositions:

31 + 509797 = 509828
61 + 509767 = 509828
97 + 509731 = 509828
139 + 509689 = 509828
181 + 509647 = 509828
271 + 509557 = 509828
307 + 509521 = 509828
379 + 509449 = 509828

Showing the first eight; more decompositions exist.
