Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989688, here are decompositions:

17 + 989671 = 989688
41 + 989647 = 989688
47 + 989641 = 989688
59 + 989629 = 989688
107 + 989581 = 989688
109 + 989579 = 989688
127 + 989561 = 989688
131 + 989557 = 989688

Showing the first eight; more decompositions exist.
