Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002658, here are decompositions:

5 + 1002653 = 1002658
11 + 1002647 = 1002658
89 + 1002569 = 1002658
131 + 1002527 = 1002658
191 + 1002467 = 1002658
281 + 1002377 = 1002658
311 + 1002347 = 1002658
317 + 1002341 = 1002658

Showing the first eight; more decompositions exist.
