Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688418, here are decompositions:

107 + 8688311 = 8688418
131 + 8688287 = 8688418
197 + 8688221 = 8688418
251 + 8688167 = 8688418
257 + 8688161 = 8688418
317 + 8688101 = 8688418
359 + 8688059 = 8688418
647 + 8687771 = 8688418

Showing the first eight; more decompositions exist.
