Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669724, here are decompositions:

23 + 8669701 = 8669724
53 + 8669671 = 8669724
67 + 8669657 = 8669724
73 + 8669651 = 8669724
97 + 8669627 = 8669724
101 + 8669623 = 8669724
103 + 8669621 = 8669724
113 + 8669611 = 8669724

Showing the first eight; more decompositions exist.
