Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688130, here are decompositions:

29 + 8688101 = 8688130
47 + 8688083 = 8688130
53 + 8688077 = 8688130
71 + 8688059 = 8688130
137 + 8687993 = 8688130
149 + 8687981 = 8688130
167 + 8687963 = 8688130
239 + 8687891 = 8688130

Showing the first eight; more decompositions exist.
