Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688556, here are decompositions:

3 + 8688553 = 8688556
5 + 8688551 = 8688556
29 + 8688527 = 8688556
59 + 8688497 = 8688556
257 + 8688299 = 8688556
269 + 8688287 = 8688556
347 + 8688209 = 8688556
353 + 8688203 = 8688556

Showing the first eight; more decompositions exist.
