Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646764, here are decompositions:

13 + 8646751 = 8646764
43 + 8646721 = 8646764
97 + 8646667 = 8646764
157 + 8646607 = 8646764
193 + 8646571 = 8646764
277 + 8646487 = 8646764
307 + 8646457 = 8646764
487 + 8646277 = 8646764

Showing the first eight; more decompositions exist.
