Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687268, here are decompositions:

19 + 8687249 = 8687268
41 + 8687227 = 8687268
59 + 8687209 = 8687268
61 + 8687207 = 8687268
71 + 8687197 = 8687268
97 + 8687171 = 8687268
127 + 8687141 = 8687268
137 + 8687131 = 8687268

Showing the first eight; more decompositions exist.
