Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989640, here are decompositions:

11 + 989629 = 989640
17 + 989623 = 989640
59 + 989581 = 989640
61 + 989579 = 989640
79 + 989561 = 989640
83 + 989557 = 989640
107 + 989533 = 989640
163 + 989477 = 989640

Showing the first eight; more decompositions exist.
