Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509778, here are decompositions:

11 + 509767 = 509778
37 + 509741 = 509778
41 + 509737 = 509778
47 + 509731 = 509778
79 + 509699 = 509778
89 + 509689 = 509778
97 + 509681 = 509778
131 + 509647 = 509778

Showing the first eight; more decompositions exist.
