Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671654, here are decompositions:

23 + 8671631 = 8671654
71 + 8671583 = 8671654
137 + 8671517 = 8671654
191 + 8671463 = 8671654
197 + 8671457 = 8671654
227 + 8671427 = 8671654
293 + 8671361 = 8671654
347 + 8671307 = 8671654

Showing the first eight; more decompositions exist.
