Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995530, here are decompositions:

17 + 995513 = 995530
59 + 995471 = 995530
83 + 995447 = 995530
131 + 995399 = 995530
149 + 995381 = 995530
167 + 995363 = 995530
191 + 995339 = 995530
227 + 995303 = 995530

Showing the first eight; more decompositions exist.
