Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985212, here are decompositions:

31 + 985181 = 985212
61 + 985151 = 985212
83 + 985129 = 985212
103 + 985109 = 985212
149 + 985063 = 985212
199 + 985013 = 985212
281 + 984931 = 985212
331 + 984881 = 985212

Showing the first eight; more decompositions exist.
