Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983820, here are decompositions:

7 + 983813 = 983820
11 + 983809 = 983820
17 + 983803 = 983820
29 + 983791 = 983820
31 + 983789 = 983820
37 + 983783 = 983820
43 + 983777 = 983820
83 + 983737 = 983820

Showing the first eight; more decompositions exist.
