Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985812, here are decompositions:

5 + 985807 = 985812
13 + 985799 = 985812
29 + 985783 = 985812
31 + 985781 = 985812
53 + 985759 = 985812
71 + 985741 = 985812
83 + 985729 = 985812
89 + 985723 = 985812

Showing the first eight; more decompositions exist.
