Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006668, here are decompositions:

17 + 1006651 = 1006668
31 + 1006637 = 1006668
59 + 1006609 = 1006668
79 + 1006589 = 1006668
109 + 1006559 = 1006668
137 + 1006531 = 1006668
197 + 1006471 = 1006668
199 + 1006469 = 1006668

Showing the first eight; more decompositions exist.
