Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008490, here are decompositions:

23 + 1008467 = 1008490
53 + 1008437 = 1008490
71 + 1008419 = 1008490
83 + 1008407 = 1008490
89 + 1008401 = 1008490
137 + 1008353 = 1008490
167 + 1008323 = 1008490
173 + 1008317 = 1008490

Showing the first eight; more decompositions exist.
