Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989918, here are decompositions:

31 + 989887 = 989918
79 + 989839 = 989918
157 + 989761 = 989918
199 + 989719 = 989918
271 + 989647 = 989918
277 + 989641 = 989918
337 + 989581 = 989918
439 + 989479 = 989918

Showing the first eight; more decompositions exist.
