Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666298, here are decompositions:

7 + 8666291 = 8666298
29 + 8666269 = 8666298
61 + 8666237 = 8666298
79 + 8666219 = 8666298
97 + 8666201 = 8666298
131 + 8666167 = 8666298
139 + 8666159 = 8666298
229 + 8666069 = 8666298

Showing the first eight; more decompositions exist.
