Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509808, here are decompositions:

7 + 509801 = 509808
11 + 509797 = 509808
41 + 509767 = 509808
67 + 509741 = 509808
71 + 509737 = 509808
109 + 509699 = 509808
127 + 509681 = 509808
149 + 509659 = 509808

Showing the first eight; more decompositions exist.
