Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647766, here are decompositions:

7 + 8647759 = 8647766
13 + 8647753 = 8647766
67 + 8647699 = 8647766
109 + 8647657 = 8647766
199 + 8647567 = 8647766
229 + 8647537 = 8647766
307 + 8647459 = 8647766
349 + 8647417 = 8647766

Showing the first eight; more decompositions exist.
