Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711320, here are decompositions:

53 + 8711267 = 8711320
83 + 8711237 = 8711320
131 + 8711189 = 8711320
179 + 8711141 = 8711320
239 + 8711081 = 8711320
269 + 8711051 = 8711320
311 + 8711009 = 8711320
347 + 8710973 = 8711320

Showing the first eight; more decompositions exist.
