Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688820, here are decompositions:

3 + 8688817 = 8688820
11 + 8688809 = 8688820
29 + 8688791 = 8688820
113 + 8688707 = 8688820
149 + 8688671 = 8688820
191 + 8688629 = 8688820
227 + 8688593 = 8688820
251 + 8688569 = 8688820

Showing the first eight; more decompositions exist.
