Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639298, here are decompositions:

7 + 8639291 = 8639298
37 + 8639261 = 8639298
47 + 8639251 = 8639298
71 + 8639227 = 8639298
79 + 8639219 = 8639298
127 + 8639171 = 8639298
137 + 8639161 = 8639298
149 + 8639149 = 8639298

Showing the first eight; more decompositions exist.
