Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985018, here are decompositions:

5 + 985013 = 985018
11 + 985007 = 985018
59 + 984959 = 985018
71 + 984947 = 985018
101 + 984917 = 985018
107 + 984911 = 985018
137 + 984881 = 985018
257 + 984761 = 985018

Showing the first eight; more decompositions exist.
