Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989868, here are decompositions:

29 + 989839 = 989868
31 + 989837 = 989868
37 + 989831 = 989868
41 + 989827 = 989868
71 + 989797 = 989868
107 + 989761 = 989868
149 + 989719 = 989868
181 + 989687 = 989868

Showing the first eight; more decompositions exist.
