Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711666, here are decompositions:

13 + 8711653 = 8711666
97 + 8711569 = 8711666
199 + 8711467 = 8711666
283 + 8711383 = 8711666
307 + 8711359 = 8711666
487 + 8711179 = 8711666
709 + 8710957 = 8711666
727 + 8710939 = 8711666

Showing the first eight; more decompositions exist.
