Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009638, here are decompositions:

11 + 1009627 = 1009638
17 + 1009621 = 1009638
29 + 1009609 = 1009638
37 + 1009601 = 1009638
79 + 1009559 = 1009638
101 + 1009537 = 1009638
107 + 1009531 = 1009638
131 + 1009507 = 1009638

Showing the first eight; more decompositions exist.
