Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989810, here are decompositions:

7 + 989803 = 989810
13 + 989797 = 989810
61 + 989749 = 989810
67 + 989743 = 989810
139 + 989671 = 989810
163 + 989647 = 989810
181 + 989629 = 989810
229 + 989581 = 989810

Showing the first eight; more decompositions exist.
