Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985240, here are decompositions:

59 + 985181 = 985240
89 + 985151 = 985240
131 + 985109 = 985240
227 + 985013 = 985240
233 + 985007 = 985240
281 + 984959 = 985240
293 + 984947 = 985240
317 + 984923 = 985240

Showing the first eight; more decompositions exist.
