Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669730, here are decompositions:

29 + 8669701 = 8669730
59 + 8669671 = 8669730
61 + 8669669 = 8669730
73 + 8669657 = 8669730
79 + 8669651 = 8669730
101 + 8669629 = 8669730
103 + 8669627 = 8669730
107 + 8669623 = 8669730

Showing the first eight; more decompositions exist.
