Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989968, here are decompositions:

17 + 989951 = 989968
29 + 989939 = 989968
47 + 989921 = 989968
59 + 989909 = 989968
131 + 989837 = 989968
137 + 989831 = 989968
191 + 989777 = 989968
281 + 989687 = 989968

Showing the first eight; more decompositions exist.
