Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989730, here are decompositions:

11 + 989719 = 989730
43 + 989687 = 989730
59 + 989671 = 989730
67 + 989663 = 989730
83 + 989647 = 989730
89 + 989641 = 989730
101 + 989629 = 989730
107 + 989623 = 989730

Showing the first eight; more decompositions exist.
