Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985638, here are decompositions:

7 + 985631 = 985638
37 + 985601 = 985638
41 + 985597 = 985638
67 + 985571 = 985638
107 + 985531 = 985638
109 + 985529 = 985638
139 + 985499 = 985638
151 + 985487 = 985638

Showing the first eight; more decompositions exist.
