Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006660, here are decompositions:

23 + 1006637 = 1006660
47 + 1006613 = 1006660
71 + 1006589 = 1006660
101 + 1006559 = 1006660
113 + 1006547 = 1006660
167 + 1006493 = 1006660
191 + 1006469 = 1006660
197 + 1006463 = 1006660

Showing the first eight; more decompositions exist.
