Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985850, here are decompositions:

31 + 985819 = 985850
43 + 985807 = 985850
67 + 985783 = 985850
109 + 985741 = 985850
127 + 985723 = 985850
193 + 985657 = 985850
211 + 985639 = 985850
331 + 985519 = 985850

Showing the first eight; more decompositions exist.
