Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688658, here are decompositions:

29 + 8688629 = 8688658
47 + 8688611 = 8688658
89 + 8688569 = 8688658
101 + 8688557 = 8688658
107 + 8688551 = 8688658
131 + 8688527 = 8688658
137 + 8688521 = 8688658
347 + 8688311 = 8688658

Showing the first eight; more decompositions exist.
