Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509820, here are decompositions:

19 + 509801 = 509820
23 + 509797 = 509820
37 + 509783 = 509820
53 + 509767 = 509820
79 + 509741 = 509820
83 + 509737 = 509820
89 + 509731 = 509820
97 + 509723 = 509820

Showing the first eight; more decompositions exist.
