Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671936, here are decompositions:

17 + 8671919 = 8671936
29 + 8671907 = 8671936
167 + 8671769 = 8671936
197 + 8671739 = 8671936
227 + 8671709 = 8671936
239 + 8671697 = 8671936
347 + 8671589 = 8671936
353 + 8671583 = 8671936

Showing the first eight; more decompositions exist.
