Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669688, here are decompositions:

17 + 8669671 = 8669688
19 + 8669669 = 8669688
31 + 8669657 = 8669688
37 + 8669651 = 8669688
59 + 8669629 = 8669688
61 + 8669627 = 8669688
67 + 8669621 = 8669688
199 + 8669489 = 8669688

Showing the first eight; more decompositions exist.
