Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995980, here are decompositions:

23 + 995957 = 995980
53 + 995927 = 995980
71 + 995909 = 995980
179 + 995801 = 995980
197 + 995783 = 995980
233 + 995747 = 995980
281 + 995699 = 995980
311 + 995669 = 995980

Showing the first eight; more decompositions exist.
