Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688270, here are decompositions:

11 + 8688259 = 8688270
61 + 8688209 = 8688270
67 + 8688203 = 8688270
103 + 8688167 = 8688270
109 + 8688161 = 8688270
113 + 8688157 = 8688270
127 + 8688143 = 8688270
137 + 8688133 = 8688270

Showing the first eight; more decompositions exist.
