Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671876, here are decompositions:

107 + 8671769 = 8671876
137 + 8671739 = 8671876
167 + 8671709 = 8671876
179 + 8671697 = 8671876
293 + 8671583 = 8671876
359 + 8671517 = 8671876
419 + 8671457 = 8671876
449 + 8671427 = 8671876

Showing the first eight; more decompositions exist.
