Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711560, here are decompositions:

17 + 8711543 = 8711560
59 + 8711501 = 8711560
71 + 8711489 = 8711560
113 + 8711447 = 8711560
173 + 8711387 = 8711560
197 + 8711363 = 8711560
227 + 8711333 = 8711560
293 + 8711267 = 8711560

Showing the first eight; more decompositions exist.
