Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006666, here are decompositions:

29 + 1006637 = 1006666
53 + 1006613 = 1006666
83 + 1006583 = 1006666
107 + 1006559 = 1006666
173 + 1006493 = 1006666
197 + 1006469 = 1006666
233 + 1006433 = 1006666
359 + 1006307 = 1006666

Showing the first eight; more decompositions exist.
