Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619798, here are decompositions:

7 + 8619791 = 8619798
79 + 8619719 = 8619798
137 + 8619661 = 8619798
149 + 8619649 = 8619798
197 + 8619601 = 8619798
211 + 8619587 = 8619798
307 + 8619491 = 8619798
337 + 8619461 = 8619798

Showing the first eight; more decompositions exist.
