Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020666, here are decompositions:

47 + 1020619 = 1020666
67 + 1020599 = 1020666
83 + 1020583 = 1020666
109 + 1020557 = 1020666
137 + 1020529 = 1020666
149 + 1020517 = 1020666
277 + 1020389 = 1020666
313 + 1020353 = 1020666

Showing the first eight; more decompositions exist.
