Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717660, here are decompositions:

37 + 8717623 = 8717660
97 + 8717563 = 8717660
103 + 8717557 = 8717660
109 + 8717551 = 8717660
139 + 8717521 = 8717660
151 + 8717509 = 8717660
271 + 8717389 = 8717660
307 + 8717353 = 8717660

Showing the first eight; more decompositions exist.
