Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688208, here are decompositions:

5 + 8688203 = 8688208
41 + 8688167 = 8688208
47 + 8688161 = 8688208
107 + 8688101 = 8688208
131 + 8688077 = 8688208
149 + 8688059 = 8688208
197 + 8688011 = 8688208
227 + 8687981 = 8688208

Showing the first eight; more decompositions exist.
