Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717666, here are decompositions:

43 + 8717623 = 8717666
103 + 8717563 = 8717666
109 + 8717557 = 8717666
157 + 8717509 = 8717666
277 + 8717389 = 8717666
313 + 8717353 = 8717666
337 + 8717329 = 8717666
379 + 8717287 = 8717666

Showing the first eight; more decompositions exist.
