Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711248, here are decompositions:

11 + 8711237 = 8711248
59 + 8711189 = 8711248
89 + 8711159 = 8711248
107 + 8711141 = 8711248
131 + 8711117 = 8711248
167 + 8711081 = 8711248
197 + 8711051 = 8711248
239 + 8711009 = 8711248

Showing the first eight; more decompositions exist.
