Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985420, here are decompositions:

3 + 985417 = 985420
17 + 985403 = 985420
41 + 985379 = 985420
89 + 985331 = 985420
113 + 985307 = 985420
167 + 985253 = 985420
239 + 985181 = 985420
269 + 985151 = 985420

Showing the first eight; more decompositions exist.
