Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005660, here are decompositions:

13 + 1005647 = 1005660
17 + 1005643 = 1005660
23 + 1005637 = 1005660
41 + 1005619 = 1005660
43 + 1005617 = 1005660
67 + 1005593 = 1005660
79 + 1005581 = 1005660
107 + 1005553 = 1005660

Showing the first eight; more decompositions exist.
