Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989930, here are decompositions:

13 + 989917 = 989930
43 + 989887 = 989930
61 + 989869 = 989930
103 + 989827 = 989930
127 + 989803 = 989930
181 + 989749 = 989930
211 + 989719 = 989930
283 + 989647 = 989930

Showing the first eight; more decompositions exist.
