Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989778, here are decompositions:

17 + 989761 = 989778
29 + 989749 = 989778
59 + 989719 = 989778
107 + 989671 = 989778
131 + 989647 = 989778
137 + 989641 = 989778
149 + 989629 = 989778
197 + 989581 = 989778

Showing the first eight; more decompositions exist.
