Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985138, here are decompositions:

17 + 985121 = 985138
29 + 985109 = 985138
41 + 985097 = 985138
59 + 985079 = 985138
131 + 985007 = 985138
179 + 984959 = 985138
191 + 984947 = 985138
227 + 984911 = 985138

Showing the first eight; more decompositions exist.
