Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717458, here are decompositions:

257 + 8717201 = 8717458
461 + 8716997 = 8717458
569 + 8716889 = 8717458
641 + 8716817 = 8717458
797 + 8716661 = 8717458
839 + 8716619 = 8717458
1019 + 8716439 = 8717458
1187 + 8716271 = 8717458

Showing the first eight; more decompositions exist.
