Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989826, here are decompositions:

23 + 989803 = 989826
29 + 989797 = 989826
43 + 989783 = 989826
73 + 989753 = 989826
83 + 989743 = 989826
107 + 989719 = 989826
139 + 989687 = 989826
163 + 989663 = 989826

Showing the first eight; more decompositions exist.
