Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985128, here are decompositions:

7 + 985121 = 985128
19 + 985109 = 985128
31 + 985097 = 985128
71 + 985057 = 985128
101 + 985027 = 985128
181 + 984947 = 985128
197 + 984931 = 985128
211 + 984917 = 985128

Showing the first eight; more decompositions exist.
