Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688918, here are decompositions:

89 + 8688829 = 8688918
101 + 8688817 = 8688918
109 + 8688809 = 8688918
127 + 8688791 = 8688918
131 + 8688787 = 8688918
179 + 8688739 = 8688918
211 + 8688707 = 8688918
307 + 8688611 = 8688918

Showing the first eight; more decompositions exist.
