Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646728, here are decompositions:

7 + 8646721 = 8646728
19 + 8646709 = 8646728
61 + 8646667 = 8646728
157 + 8646571 = 8646728
199 + 8646529 = 8646728
241 + 8646487 = 8646728
271 + 8646457 = 8646728
367 + 8646361 = 8646728

Showing the first eight; more decompositions exist.
