Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711728, here are decompositions:

59 + 8711669 = 8711728
71 + 8711657 = 8711728
101 + 8711627 = 8711728
107 + 8711621 = 8711728
167 + 8711561 = 8711728
227 + 8711501 = 8711728
239 + 8711489 = 8711728
281 + 8711447 = 8711728

Showing the first eight; more decompositions exist.
