Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688678, here are decompositions:

7 + 8688671 = 8688678
67 + 8688611 = 8688678
71 + 8688607 = 8688678
101 + 8688577 = 8688678
107 + 8688571 = 8688678
109 + 8688569 = 8688678
127 + 8688551 = 8688678
151 + 8688527 = 8688678

Showing the first eight; more decompositions exist.
