Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688894, here are decompositions:

31 + 8688863 = 8688894
103 + 8688791 = 8688894
107 + 8688787 = 8688894
191 + 8688703 = 8688894
197 + 8688697 = 8688894
223 + 8688671 = 8688894
281 + 8688613 = 8688894
283 + 8688611 = 8688894

Showing the first eight; more decompositions exist.
