Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989910, here are decompositions:

23 + 989887 = 989910
37 + 989873 = 989910
41 + 989869 = 989910
71 + 989839 = 989910
73 + 989837 = 989910
79 + 989831 = 989910
83 + 989827 = 989910
107 + 989803 = 989910

Showing the first eight; more decompositions exist.
