Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711278, here are decompositions:

11 + 8711267 = 8711278
41 + 8711237 = 8711278
89 + 8711189 = 8711278
137 + 8711141 = 8711278
197 + 8711081 = 8711278
227 + 8711051 = 8711278
269 + 8711009 = 8711278
311 + 8710967 = 8711278

Showing the first eight; more decompositions exist.
