Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985782, here are decompositions:

23 + 985759 = 985782
41 + 985741 = 985782
53 + 985729 = 985782
59 + 985723 = 985782
73 + 985709 = 985782
79 + 985703 = 985782
103 + 985679 = 985782
151 + 985631 = 985782

Showing the first eight; more decompositions exist.
