Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647798, here are decompositions:

59 + 8647739 = 8647798
101 + 8647697 = 8647798
389 + 8647409 = 8647798
431 + 8647367 = 8647798
449 + 8647349 = 8647798
521 + 8647277 = 8647798
569 + 8647229 = 8647798
617 + 8647181 = 8647798

Showing the first eight; more decompositions exist.
