Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985668, here are decompositions:

11 + 985657 = 985668
29 + 985639 = 985668
37 + 985631 = 985668
67 + 985601 = 985668
71 + 985597 = 985668
97 + 985571 = 985668
137 + 985531 = 985668
139 + 985529 = 985668

Showing the first eight; more decompositions exist.
