Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671666, here are decompositions:

83 + 8671583 = 8671666
149 + 8671517 = 8671666
167 + 8671499 = 8671666
197 + 8671469 = 8671666
239 + 8671427 = 8671666
257 + 8671409 = 8671666
359 + 8671307 = 8671666
569 + 8671097 = 8671666

Showing the first eight; more decompositions exist.
