Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509768, here are decompositions:

31 + 509737 = 509768
37 + 509731 = 509768
79 + 509689 = 509768
109 + 509659 = 509768
199 + 509569 = 509768
211 + 509557 = 509768
379 + 509389 = 509768
409 + 509359 = 509768

Showing the first eight; more decompositions exist.
