Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985130, here are decompositions:

67 + 985063 = 985130
73 + 985057 = 985130
103 + 985027 = 985130
127 + 985003 = 985130
199 + 984931 = 985130
271 + 984859 = 985130
277 + 984853 = 985130
283 + 984847 = 985130

Showing the first eight; more decompositions exist.
