Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995142, here are decompositions:

23 + 995119 = 995142
61 + 995081 = 995142
89 + 995053 = 995142
151 + 994991 = 995142
179 + 994963 = 995142
193 + 994949 = 995142
229 + 994913 = 995142
241 + 994901 = 995142

Showing the first eight; more decompositions exist.
