Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509812, here are decompositions:

11 + 509801 = 509812
29 + 509783 = 509812
71 + 509741 = 509812
89 + 509723 = 509812
113 + 509699 = 509812
131 + 509681 = 509812
179 + 509633 = 509812
239 + 509573 = 509812

Showing the first eight; more decompositions exist.
