Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985080, here are decompositions:

17 + 985063 = 985080
23 + 985057 = 985080
53 + 985027 = 985080
67 + 985013 = 985080
73 + 985007 = 985080
149 + 984931 = 985080
157 + 984923 = 985080
163 + 984917 = 985080

Showing the first eight; more decompositions exist.
