Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008658, here are decompositions:

41 + 1008617 = 1008658
47 + 1008611 = 1008658
71 + 1008587 = 1008658
191 + 1008467 = 1008658
239 + 1008419 = 1008658
251 + 1008407 = 1008658
257 + 1008401 = 1008658
311 + 1008347 = 1008658

Showing the first eight; more decompositions exist.
