Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985090, here are decompositions:

11 + 985079 = 985090
83 + 985007 = 985090
131 + 984959 = 985090
167 + 984923 = 985090
173 + 984917 = 985090
179 + 984911 = 985090
383 + 984707 = 985090
389 + 984701 = 985090

Showing the first eight; more decompositions exist.
