Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989784, here are decompositions:

7 + 989777 = 989784
23 + 989761 = 989784
31 + 989753 = 989784
41 + 989743 = 989784
97 + 989687 = 989784
113 + 989671 = 989784
137 + 989647 = 989784
223 + 989561 = 989784

Showing the first eight; more decompositions exist.
