Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985500, here are decompositions:

7 + 985493 = 985500
13 + 985487 = 985500
17 + 985483 = 985500
29 + 985471 = 985500
37 + 985463 = 985500
53 + 985447 = 985500
67 + 985433 = 985500
83 + 985417 = 985500

Showing the first eight; more decompositions exist.
