Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509826, here are decompositions:

29 + 509797 = 509826
43 + 509783 = 509826
59 + 509767 = 509826
89 + 509737 = 509826
103 + 509723 = 509826
127 + 509699 = 509826
137 + 509689 = 509826
139 + 509687 = 509826

Showing the first eight; more decompositions exist.
