Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009866, here are decompositions:

7 + 1009859 = 1009866
23 + 1009843 = 1009866
29 + 1009837 = 1009866
47 + 1009819 = 1009866
59 + 1009807 = 1009866
79 + 1009787 = 1009866
139 + 1009727 = 1009866
197 + 1009669 = 1009866

Showing the first eight; more decompositions exist.
