Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985390, here are decompositions:

11 + 985379 = 985390
59 + 985331 = 985390
83 + 985307 = 985390
89 + 985301 = 985390
113 + 985277 = 985390
137 + 985253 = 985390
239 + 985151 = 985390
269 + 985121 = 985390

Showing the first eight; more decompositions exist.
