Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006640, here are decompositions:

3 + 1006637 = 1006640
7 + 1006633 = 1006640
31 + 1006609 = 1006640
97 + 1006543 = 1006640
109 + 1006531 = 1006640
127 + 1006513 = 1006640
199 + 1006441 = 1006640
307 + 1006333 = 1006640

Showing the first eight; more decompositions exist.
