Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020866, here are decompositions:

13 + 1020853 = 1020866
19 + 1020847 = 1020866
43 + 1020823 = 1020866
109 + 1020757 = 1020866
157 + 1020709 = 1020866
199 + 1020667 = 1020866
277 + 1020589 = 1020866
283 + 1020583 = 1020866

Showing the first eight; more decompositions exist.
