Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985790, here are decompositions:

7 + 985783 = 985790
31 + 985759 = 985790
61 + 985729 = 985790
67 + 985723 = 985790
151 + 985639 = 985790
193 + 985597 = 985790
271 + 985519 = 985790
307 + 985483 = 985790

Showing the first eight; more decompositions exist.
