Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985156, here are decompositions:

5 + 985151 = 985156
47 + 985109 = 985156
59 + 985097 = 985156
149 + 985007 = 985156
197 + 984959 = 985156
233 + 984923 = 985156
239 + 984917 = 985156
449 + 984707 = 985156

Showing the first eight; more decompositions exist.
