Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989836, here are decompositions:

5 + 989831 = 989836
53 + 989783 = 989836
59 + 989777 = 989836
83 + 989753 = 989836
149 + 989687 = 989836
173 + 989663 = 989836
257 + 989579 = 989836
359 + 989477 = 989836

Showing the first eight; more decompositions exist.
