Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688078, here are decompositions:

11 + 8688067 = 8688078
19 + 8688059 = 8688078
67 + 8688011 = 8688078
97 + 8687981 = 8688078
149 + 8687929 = 8688078
167 + 8687911 = 8688078
197 + 8687881 = 8688078
199 + 8687879 = 8688078

Showing the first eight; more decompositions exist.
