Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687118, here are decompositions:

29 + 8687089 = 8687118
31 + 8687087 = 8687118
137 + 8686981 = 8687118
157 + 8686961 = 8687118
229 + 8686889 = 8687118
241 + 8686877 = 8687118
277 + 8686841 = 8687118
311 + 8686807 = 8687118

Showing the first eight; more decompositions exist.
