Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627238, here are decompositions:

47 + 8627191 = 8627238
71 + 8627167 = 8627238
89 + 8627149 = 8627238
97 + 8627141 = 8627238
127 + 8627111 = 8627238
157 + 8627081 = 8627238
181 + 8627057 = 8627238
239 + 8626999 = 8627238

Showing the first eight; more decompositions exist.
