Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995500, here are decompositions:

29 + 995471 = 995500
53 + 995447 = 995500
101 + 995399 = 995500
113 + 995387 = 995500
131 + 995369 = 995500
137 + 995363 = 995500
173 + 995327 = 995500
197 + 995303 = 995500

Showing the first eight; more decompositions exist.
