Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716440, here are decompositions:

11 + 8716429 = 8716440
59 + 8716381 = 8716440
67 + 8716373 = 8716440
151 + 8716289 = 8716440
157 + 8716283 = 8716440
191 + 8716249 = 8716440
197 + 8716243 = 8716440
223 + 8716217 = 8716440

Showing the first eight; more decompositions exist.
