Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671756, here are decompositions:

17 + 8671739 = 8671756
47 + 8671709 = 8671756
59 + 8671697 = 8671756
167 + 8671589 = 8671756
173 + 8671583 = 8671756
239 + 8671517 = 8671756
257 + 8671499 = 8671756
293 + 8671463 = 8671756

Showing the first eight; more decompositions exist.
