Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668960, here are decompositions:

59 + 8668901 = 8668960
71 + 8668889 = 8668960
197 + 8668763 = 8668960
239 + 8668721 = 8668960
263 + 8668697 = 8668960
317 + 8668643 = 8668960
347 + 8668613 = 8668960
383 + 8668577 = 8668960

Showing the first eight; more decompositions exist.
