Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989828, here are decompositions:

31 + 989797 = 989828
67 + 989761 = 989828
79 + 989749 = 989828
109 + 989719 = 989828
157 + 989671 = 989828
181 + 989647 = 989828
199 + 989629 = 989828
271 + 989557 = 989828

Showing the first eight; more decompositions exist.
