Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995990, here are decompositions:

3 + 995987 = 995990
7 + 995983 = 995990
31 + 995959 = 995990
103 + 995887 = 995990
109 + 995881 = 995990
157 + 995833 = 995990
199 + 995791 = 995990
271 + 995719 = 995990

Showing the first eight; more decompositions exist.
