Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688132, here are decompositions:

23 + 8688109 = 8688132
31 + 8688101 = 8688132
73 + 8688059 = 8688132
139 + 8687993 = 8688132
149 + 8687983 = 8688132
151 + 8687981 = 8688132
179 + 8687953 = 8688132
241 + 8687891 = 8688132

Showing the first eight; more decompositions exist.
