Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628318, here are decompositions:

47 + 8628271 = 8628318
131 + 8628187 = 8628318
137 + 8628181 = 8628318
157 + 8628161 = 8628318
197 + 8628121 = 8628318
211 + 8628107 = 8628318
241 + 8628077 = 8628318
269 + 8628049 = 8628318

Showing the first eight; more decompositions exist.
