Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687266, here are decompositions:

17 + 8687249 = 8687266
53 + 8687213 = 8687266
59 + 8687207 = 8687266
83 + 8687183 = 8687266
149 + 8687117 = 8687266
173 + 8687093 = 8687266
179 + 8687087 = 8687266
197 + 8687069 = 8687266

Showing the first eight; more decompositions exist.
