Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686418, here are decompositions:

109 + 8686309 = 8686418
127 + 8686291 = 8686418
211 + 8686207 = 8686418
229 + 8686189 = 8686418
241 + 8686177 = 8686418
271 + 8686147 = 8686418
277 + 8686141 = 8686418
331 + 8686087 = 8686418

Showing the first eight; more decompositions exist.
