Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716428, here are decompositions:

47 + 8716381 = 8716428
139 + 8716289 = 8716428
157 + 8716271 = 8716428
179 + 8716249 = 8716428
191 + 8716237 = 8716428
211 + 8716217 = 8716428
241 + 8716187 = 8716428
269 + 8716159 = 8716428

Showing the first eight; more decompositions exist.
