Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995818, here are decompositions:

17 + 995801 = 995818
71 + 995747 = 995818
149 + 995669 = 995818
167 + 995651 = 995818
227 + 995591 = 995818
251 + 995567 = 995818
269 + 995549 = 995818
347 + 995471 = 995818

Showing the first eight; more decompositions exist.
