Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647960, here are decompositions:

11 + 8647949 = 8647960
23 + 8647937 = 8647960
47 + 8647913 = 8647960
71 + 8647889 = 8647960
137 + 8647823 = 8647960
263 + 8647697 = 8647960
449 + 8647511 = 8647960
491 + 8647469 = 8647960

Showing the first eight; more decompositions exist.
