Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989820, here are decompositions:

17 + 989803 = 989820
23 + 989797 = 989820
37 + 989783 = 989820
43 + 989777 = 989820
59 + 989761 = 989820
67 + 989753 = 989820
71 + 989749 = 989820
101 + 989719 = 989820

Showing the first eight; more decompositions exist.
