Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985312, here are decompositions:

5 + 985307 = 985312
11 + 985301 = 985312
59 + 985253 = 985312
131 + 985181 = 985312
191 + 985121 = 985312
233 + 985079 = 985312
353 + 984959 = 985312
389 + 984923 = 985312

Showing the first eight; more decompositions exist.
