Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985228, here are decompositions:

47 + 985181 = 985228
107 + 985121 = 985228
131 + 985097 = 985228
149 + 985079 = 985228
269 + 984959 = 985228
281 + 984947 = 985228
311 + 984917 = 985228
317 + 984911 = 985228

Showing the first eight; more decompositions exist.
