Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669658, here are decompositions:

7 + 8669651 = 8669658
29 + 8669629 = 8669658
31 + 8669627 = 8669658
37 + 8669621 = 8669658
47 + 8669611 = 8669658
131 + 8669527 = 8669658
157 + 8669501 = 8669658
181 + 8669477 = 8669658

Showing the first eight; more decompositions exist.
