Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009686, here are decompositions:

17 + 1009669 = 1009686
37 + 1009649 = 1009686
43 + 1009643 = 1009686
59 + 1009627 = 1009686
113 + 1009573 = 1009686
127 + 1009559 = 1009686
149 + 1009537 = 1009686
179 + 1009507 = 1009686

Showing the first eight; more decompositions exist.
