Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006680, here are decompositions:

29 + 1006651 = 1006680
43 + 1006637 = 1006680
47 + 1006633 = 1006680
67 + 1006613 = 1006680
71 + 1006609 = 1006680
97 + 1006583 = 1006680
137 + 1006543 = 1006680
149 + 1006531 = 1006680

Showing the first eight; more decompositions exist.
