Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985740, here are decompositions:

11 + 985729 = 985740
17 + 985723 = 985740
31 + 985709 = 985740
37 + 985703 = 985740
61 + 985679 = 985740
73 + 985667 = 985740
83 + 985657 = 985740
101 + 985639 = 985740

Showing the first eight; more decompositions exist.
