Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669670, here are decompositions:

13 + 8669657 = 8669670
19 + 8669651 = 8669670
41 + 8669629 = 8669670
43 + 8669627 = 8669670
47 + 8669623 = 8669670
59 + 8669611 = 8669670
127 + 8669543 = 8669670
157 + 8669513 = 8669670

Showing the first eight; more decompositions exist.
