Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995638, here are decompositions:

47 + 995591 = 995638
71 + 995567 = 995638
89 + 995549 = 995638
107 + 995531 = 995638
167 + 995471 = 995638
191 + 995447 = 995638
239 + 995399 = 995638
251 + 995387 = 995638

Showing the first eight; more decompositions exist.
