Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688800, here are decompositions:

13 + 8688787 = 8688800
61 + 8688739 = 8688800
97 + 8688703 = 8688800
103 + 8688697 = 8688800
193 + 8688607 = 8688800
199 + 8688601 = 8688800
223 + 8688577 = 8688800
229 + 8688571 = 8688800

Showing the first eight; more decompositions exist.
