Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509850, here are decompositions:

7 + 509843 = 509850
13 + 509837 = 509850
17 + 509833 = 509850
53 + 509797 = 509850
67 + 509783 = 509850
83 + 509767 = 509850
109 + 509741 = 509850
113 + 509737 = 509850

Showing the first eight; more decompositions exist.
