Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020806, here are decompositions:

97 + 1020709 = 1020806
139 + 1020667 = 1020806
223 + 1020583 = 1020806
277 + 1020529 = 1020806
349 + 1020457 = 1020806
547 + 1020259 = 1020806
643 + 1020163 = 1020806
727 + 1020079 = 1020806

Showing the first eight; more decompositions exist.
