Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688888, here are decompositions:

59 + 8688829 = 8688888
71 + 8688817 = 8688888
79 + 8688809 = 8688888
97 + 8688791 = 8688888
101 + 8688787 = 8688888
149 + 8688739 = 8688888
181 + 8688707 = 8688888
191 + 8688697 = 8688888

Showing the first eight; more decompositions exist.
