Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688028, here are decompositions:

17 + 8688011 = 8688028
47 + 8687981 = 8688028
137 + 8687891 = 8688028
149 + 8687879 = 8688028
257 + 8687771 = 8688028
269 + 8687759 = 8688028
359 + 8687669 = 8688028
599 + 8687429 = 8688028

Showing the first eight; more decompositions exist.
