Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989866, here are decompositions:

29 + 989837 = 989866
83 + 989783 = 989866
89 + 989777 = 989866
113 + 989753 = 989866
179 + 989687 = 989866
359 + 989507 = 989866
389 + 989477 = 989866
443 + 989423 = 989866

Showing the first eight; more decompositions exist.
