Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621298, here are decompositions:

17 + 8621281 = 8621298
61 + 8621237 = 8621298
89 + 8621209 = 8621298
97 + 8621201 = 8621298
109 + 8621189 = 8621298
151 + 8621147 = 8621298
197 + 8621101 = 8621298
211 + 8621087 = 8621298

Showing the first eight; more decompositions exist.
