Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989790, here are decompositions:

7 + 989783 = 989790
13 + 989777 = 989790
29 + 989761 = 989790
37 + 989753 = 989790
41 + 989749 = 989790
47 + 989743 = 989790
71 + 989719 = 989790
103 + 989687 = 989790

Showing the first eight; more decompositions exist.
