Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688458, here are decompositions:

61 + 8688397 = 8688458
109 + 8688349 = 8688458
199 + 8688259 = 8688458
349 + 8688109 = 8688458
547 + 8687911 = 8688458
577 + 8687881 = 8688458
631 + 8687827 = 8688458
661 + 8687797 = 8688458

Showing the first eight; more decompositions exist.
