Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989772, here are decompositions:

11 + 989761 = 989772
19 + 989753 = 989772
23 + 989749 = 989772
29 + 989743 = 989772
53 + 989719 = 989772
101 + 989671 = 989772
109 + 989663 = 989772
131 + 989641 = 989772

Showing the first eight; more decompositions exist.
