Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989684, here are decompositions:

13 + 989671 = 989684
37 + 989647 = 989684
43 + 989641 = 989684
61 + 989623 = 989684
103 + 989581 = 989684
127 + 989557 = 989684
151 + 989533 = 989684
307 + 989377 = 989684

Showing the first eight; more decompositions exist.
