Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038660, here are decompositions:

17 + 1038643 = 1038660
23 + 1038637 = 1038660
31 + 1038629 = 1038660
37 + 1038623 = 1038660
41 + 1038619 = 1038660
43 + 1038617 = 1038660
59 + 1038601 = 1038660
61 + 1038599 = 1038660

Showing the first eight; more decompositions exist.
