Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688478, here are decompositions:

41 + 8688437 = 8688478
167 + 8688311 = 8688478
179 + 8688299 = 8688478
191 + 8688287 = 8688478
257 + 8688221 = 8688478
269 + 8688209 = 8688478
311 + 8688167 = 8688478
317 + 8688161 = 8688478

Showing the first eight; more decompositions exist.
