Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688328, here are decompositions:

17 + 8688311 = 8688328
29 + 8688299 = 8688328
41 + 8688287 = 8688328
107 + 8688221 = 8688328
167 + 8688161 = 8688328
227 + 8688101 = 8688328
251 + 8688077 = 8688328
269 + 8688059 = 8688328

Showing the first eight; more decompositions exist.
