Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995538, here are decompositions:

7 + 995531 = 995538
67 + 995471 = 995538
107 + 995431 = 995538
139 + 995399 = 995538
151 + 995387 = 995538
157 + 995381 = 995538
191 + 995347 = 995538
197 + 995341 = 995538

Showing the first eight; more decompositions exist.
