Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509740, here are decompositions:

3 + 509737 = 509740
17 + 509723 = 509740
41 + 509699 = 509740
47 + 509693 = 509740
53 + 509687 = 509740
59 + 509681 = 509740
107 + 509633 = 509740
137 + 509603 = 509740

Showing the first eight; more decompositions exist.
