Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715664, here are decompositions:

5 + 8715659 = 8715664
11 + 8715653 = 8715664
17 + 8715647 = 8715664
47 + 8715617 = 8715664
233 + 8715431 = 8715664
263 + 8715401 = 8715664
281 + 8715383 = 8715664
317 + 8715347 = 8715664

Showing the first eight; more decompositions exist.
