Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989958, here are decompositions:

7 + 989951 = 989958
19 + 989939 = 989958
29 + 989929 = 989958
37 + 989921 = 989958
41 + 989917 = 989958
71 + 989887 = 989958
89 + 989869 = 989958
127 + 989831 = 989958

Showing the first eight; more decompositions exist.
