Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995872, here are decompositions:

71 + 995801 = 995872
89 + 995783 = 995872
173 + 995699 = 995872
281 + 995591 = 995872
359 + 995513 = 995872
401 + 995471 = 995872
491 + 995381 = 995872
503 + 995369 = 995872

Showing the first eight; more decompositions exist.
