Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509836, here are decompositions:

3 + 509833 = 509836
53 + 509783 = 509836
113 + 509723 = 509836
137 + 509699 = 509836
149 + 509687 = 509836
233 + 509603 = 509836
263 + 509573 = 509836
293 + 509543 = 509836

Showing the first eight; more decompositions exist.
