Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985000, here are decompositions:

41 + 984959 = 985000
53 + 984947 = 985000
83 + 984917 = 985000
89 + 984911 = 985000
239 + 984761 = 985000
251 + 984749 = 985000
293 + 984707 = 985000
311 + 984689 = 985000

Showing the first eight; more decompositions exist.
