Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008646, here are decompositions:

29 + 1008617 = 1008646
59 + 1008587 = 1008646
83 + 1008563 = 1008646
179 + 1008467 = 1008646
227 + 1008419 = 1008646
239 + 1008407 = 1008646
293 + 1008353 = 1008646
383 + 1008263 = 1008646

Showing the first eight; more decompositions exist.
