Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717188, here are decompositions:

17 + 8717171 = 8717188
71 + 8717117 = 8717188
167 + 8717021 = 8717188
191 + 8716997 = 8717188
269 + 8716919 = 8717188
419 + 8716769 = 8717188
461 + 8716727 = 8717188
479 + 8716709 = 8717188

Showing the first eight; more decompositions exist.
