Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669718, here are decompositions:

17 + 8669701 = 8669718
47 + 8669671 = 8669718
61 + 8669657 = 8669718
67 + 8669651 = 8669718
89 + 8669629 = 8669718
97 + 8669621 = 8669718
107 + 8669611 = 8669718
191 + 8669527 = 8669718

Showing the first eight; more decompositions exist.
