Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009918, here are decompositions:

17 + 1009901 = 1009918
59 + 1009859 = 1009918
131 + 1009787 = 1009918
137 + 1009781 = 1009918
191 + 1009727 = 1009918
269 + 1009649 = 1009918
281 + 1009637 = 1009918
317 + 1009601 = 1009918

Showing the first eight; more decompositions exist.
