Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509782, here are decompositions:

41 + 509741 = 509782
59 + 509723 = 509782
83 + 509699 = 509782
89 + 509693 = 509782
101 + 509681 = 509782
149 + 509633 = 509782
179 + 509603 = 509782
191 + 509591 = 509782

Showing the first eight; more decompositions exist.
