Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717938, here are decompositions:

11 + 8717927 = 8717938
29 + 8717909 = 8717938
71 + 8717867 = 8717938
191 + 8717747 = 8717938
197 + 8717741 = 8717938
347 + 8717591 = 8717938
821 + 8717117 = 8717938
941 + 8716997 = 8717938

Showing the first eight; more decompositions exist.
