Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687306, here are decompositions:

3 + 8687303 = 8687306
7 + 8687299 = 8687306
73 + 8687233 = 8687306
79 + 8687227 = 8687306
97 + 8687209 = 8687306
109 + 8687197 = 8687306
157 + 8687149 = 8687306
307 + 8686999 = 8687306

Showing the first eight; more decompositions exist.
