Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711238, here are decompositions:

59 + 8711179 = 8711238
79 + 8711159 = 8711238
97 + 8711141 = 8711238
101 + 8711137 = 8711238
157 + 8711081 = 8711238
167 + 8711071 = 8711238
227 + 8711011 = 8711238
229 + 8711009 = 8711238

Showing the first eight; more decompositions exist.
