Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711646, here are decompositions:

19 + 8711627 = 8711646
29 + 8711617 = 8711646
43 + 8711603 = 8711646
103 + 8711543 = 8711646
113 + 8711533 = 8711646
157 + 8711489 = 8711646
179 + 8711467 = 8711646
199 + 8711447 = 8711646

Showing the first eight; more decompositions exist.
