Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688756, here are decompositions:

17 + 8688739 = 8688756
53 + 8688703 = 8688756
59 + 8688697 = 8688756
127 + 8688629 = 8688756
149 + 8688607 = 8688756
163 + 8688593 = 8688756
173 + 8688583 = 8688756
179 + 8688577 = 8688756

Showing the first eight; more decompositions exist.
