Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509862, here are decompositions:

19 + 509843 = 509862
29 + 509833 = 509862
61 + 509801 = 509862
79 + 509783 = 509862
131 + 509731 = 509862
139 + 509723 = 509862
163 + 509699 = 509862
173 + 509689 = 509862

Showing the first eight; more decompositions exist.
