Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989946, here are decompositions:

7 + 989939 = 989946
17 + 989929 = 989946
29 + 989917 = 989946
37 + 989909 = 989946
59 + 989887 = 989946
73 + 989873 = 989946
107 + 989839 = 989946
109 + 989837 = 989946

Showing the first eight; more decompositions exist.
