Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688828, here are decompositions:

11 + 8688817 = 8688828
19 + 8688809 = 8688828
37 + 8688791 = 8688828
41 + 8688787 = 8688828
89 + 8688739 = 8688828
131 + 8688697 = 8688828
157 + 8688671 = 8688828
199 + 8688629 = 8688828

Showing the first eight; more decompositions exist.
