Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982820, here are decompositions:

19 + 982801 = 982820
31 + 982789 = 982820
37 + 982783 = 982820
43 + 982777 = 982820
61 + 982759 = 982820
79 + 982741 = 982820
127 + 982693 = 982820
199 + 982621 = 982820

Showing the first eight; more decompositions exist.
