Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688378, here are decompositions:

29 + 8688349 = 8688378
67 + 8688311 = 8688378
79 + 8688299 = 8688378
107 + 8688271 = 8688378
157 + 8688221 = 8688378
211 + 8688167 = 8688378
269 + 8688109 = 8688378
277 + 8688101 = 8688378

Showing the first eight; more decompositions exist.
