Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647886, here are decompositions:

7 + 8647879 = 8647886
67 + 8647819 = 8647886
103 + 8647783 = 8647886
127 + 8647759 = 8647886
229 + 8647657 = 8647886
307 + 8647579 = 8647886
349 + 8647537 = 8647886
439 + 8647447 = 8647886

Showing the first eight; more decompositions exist.
