Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989690, here are decompositions:

3 + 989687 = 989690
19 + 989671 = 989690
43 + 989647 = 989690
61 + 989629 = 989690
67 + 989623 = 989690
109 + 989581 = 989690
157 + 989533 = 989690
211 + 989479 = 989690

Showing the first eight; more decompositions exist.
