Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985290, here are decompositions:

11 + 985279 = 985290
13 + 985277 = 985290
37 + 985253 = 985290
71 + 985219 = 985290
109 + 985181 = 985290
113 + 985177 = 985290
139 + 985151 = 985290
181 + 985109 = 985290

Showing the first eight; more decompositions exist.
