Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688700, here are decompositions:

3 + 8688697 = 8688700
29 + 8688671 = 8688700
71 + 8688629 = 8688700
89 + 8688611 = 8688700
107 + 8688593 = 8688700
131 + 8688569 = 8688700
149 + 8688551 = 8688700
173 + 8688527 = 8688700

Showing the first eight; more decompositions exist.
