Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995188, here are decompositions:

41 + 995147 = 995188
71 + 995117 = 995188
107 + 995081 = 995188
137 + 995051 = 995188
179 + 995009 = 995188
191 + 994997 = 995188
197 + 994991 = 995188
239 + 994949 = 995188

Showing the first eight; more decompositions exist.
