Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647776, here are decompositions:

17 + 8647759 = 8647776
23 + 8647753 = 8647776
37 + 8647739 = 8647776
79 + 8647697 = 8647776
197 + 8647579 = 8647776
239 + 8647537 = 8647776
307 + 8647469 = 8647776
317 + 8647459 = 8647776

Showing the first eight; more decompositions exist.
