Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717398, here are decompositions:

5 + 8717393 = 8717398
197 + 8717201 = 8717398
227 + 8717171 = 8717398
281 + 8717117 = 8717398
401 + 8716997 = 8717398
479 + 8716919 = 8717398
509 + 8716889 = 8717398
719 + 8716679 = 8717398

Showing the first eight; more decompositions exist.
