Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985120, here are decompositions:

11 + 985109 = 985120
23 + 985097 = 985120
41 + 985079 = 985120
107 + 985013 = 985120
113 + 985007 = 985120
173 + 984947 = 985120
197 + 984923 = 985120
239 + 984881 = 985120

Showing the first eight; more decompositions exist.
