Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688474, here are decompositions:

5 + 8688469 = 8688474
37 + 8688437 = 8688474
163 + 8688311 = 8688474
191 + 8688283 = 8688474
271 + 8688203 = 8688474
307 + 8688167 = 8688474
313 + 8688161 = 8688474
317 + 8688157 = 8688474

Showing the first eight; more decompositions exist.
