Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688726, here are decompositions:

19 + 8688707 = 8688726
23 + 8688703 = 8688726
29 + 8688697 = 8688726
97 + 8688629 = 8688726
113 + 8688613 = 8688726
149 + 8688577 = 8688726
157 + 8688569 = 8688726
173 + 8688553 = 8688726

Showing the first eight; more decompositions exist.
