Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711686, here are decompositions:

3 + 8711683 = 8711686
17 + 8711669 = 8711686
29 + 8711657 = 8711686
59 + 8711627 = 8711686
83 + 8711603 = 8711686
197 + 8711489 = 8711686
239 + 8711447 = 8711686
353 + 8711333 = 8711686

Showing the first eight; more decompositions exist.
