Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985720, here are decompositions:

11 + 985709 = 985720
17 + 985703 = 985720
41 + 985679 = 985720
53 + 985667 = 985720
89 + 985631 = 985720
107 + 985613 = 985720
149 + 985571 = 985720
173 + 985547 = 985720

Showing the first eight; more decompositions exist.
