Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702664, here are decompositions:

17 + 8702647 = 8702664
67 + 8702597 = 8702664
71 + 8702593 = 8702664
73 + 8702591 = 8702664
107 + 8702557 = 8702664
167 + 8702497 = 8702664
181 + 8702483 = 8702664
233 + 8702431 = 8702664

Showing the first eight; more decompositions exist.
