Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995988, here are decompositions:

5 + 995983 = 995988
29 + 995959 = 995988
31 + 995957 = 995988
47 + 995941 = 995988
61 + 995927 = 995988
79 + 995909 = 995988
101 + 995887 = 995988
107 + 995881 = 995988

Showing the first eight; more decompositions exist.
