Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509750, here are decompositions:

13 + 509737 = 509750
19 + 509731 = 509750
61 + 509689 = 509750
97 + 509653 = 509750
103 + 509647 = 509750
127 + 509623 = 509750
181 + 509569 = 509750
193 + 509557 = 509750

Showing the first eight; more decompositions exist.
