Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627328, here are decompositions:

7 + 8627321 = 8627328
29 + 8627299 = 8627328
71 + 8627257 = 8627328
137 + 8627191 = 8627328
167 + 8627161 = 8627328
179 + 8627149 = 8627328
181 + 8627147 = 8627328
271 + 8627057 = 8627328

Showing the first eight; more decompositions exist.
