Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688280, here are decompositions:

59 + 8688221 = 8688280
71 + 8688209 = 8688280
113 + 8688167 = 8688280
137 + 8688143 = 8688280
179 + 8688101 = 8688280
197 + 8688083 = 8688280
269 + 8688011 = 8688280
317 + 8687963 = 8688280

Showing the first eight; more decompositions exist.
