Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717386, here are decompositions:

113 + 8717273 = 8717386
173 + 8717213 = 8717386
263 + 8717123 = 8717386
269 + 8717117 = 8717386
389 + 8716997 = 8717386
443 + 8716943 = 8717386
467 + 8716919 = 8717386
569 + 8716817 = 8717386

Showing the first eight; more decompositions exist.
