Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688388, here are decompositions:

89 + 8688299 = 8688388
101 + 8688287 = 8688388
167 + 8688221 = 8688388
179 + 8688209 = 8688388
227 + 8688161 = 8688388
311 + 8688077 = 8688388
509 + 8687879 = 8688388
617 + 8687771 = 8688388

Showing the first eight; more decompositions exist.
