Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670660, here are decompositions:

7 + 8670653 = 8670660
23 + 8670637 = 8670660
41 + 8670619 = 8670660
71 + 8670589 = 8670660
101 + 8670559 = 8670660
107 + 8670553 = 8670660
109 + 8670551 = 8670660
127 + 8670533 = 8670660

Showing the first eight; more decompositions exist.
