Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995158, here are decompositions:

11 + 995147 = 995158
41 + 995117 = 995158
107 + 995051 = 995158
149 + 995009 = 995158
167 + 994991 = 995158
251 + 994907 = 995158
257 + 994901 = 995158
347 + 994811 = 995158

Showing the first eight; more decompositions exist.
