Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620798, here are decompositions:

41 + 8620757 = 8620798
59 + 8620739 = 8620798
71 + 8620727 = 8620798
107 + 8620691 = 8620798
167 + 8620631 = 8620798
227 + 8620571 = 8620798
269 + 8620529 = 8620798
449 + 8620349 = 8620798

Showing the first eight; more decompositions exist.
