Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711328, here are decompositions:

61 + 8711267 = 8711328
139 + 8711189 = 8711328
149 + 8711179 = 8711328
167 + 8711161 = 8711328
191 + 8711137 = 8711328
211 + 8711117 = 8711328
257 + 8711071 = 8711328
277 + 8711051 = 8711328

Showing the first eight; more decompositions exist.
