Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688840, here are decompositions:

11 + 8688829 = 8688840
23 + 8688817 = 8688840
31 + 8688809 = 8688840
53 + 8688787 = 8688840
101 + 8688739 = 8688840
137 + 8688703 = 8688840
211 + 8688629 = 8688840
227 + 8688613 = 8688840

Showing the first eight; more decompositions exist.
