Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008628, here are decompositions:

11 + 1008617 = 1008628
17 + 1008611 = 1008628
41 + 1008587 = 1008628
191 + 1008437 = 1008628
227 + 1008401 = 1008628
281 + 1008347 = 1008628
311 + 1008317 = 1008628
389 + 1008239 = 1008628

Showing the first eight; more decompositions exist.
