Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688528, here are decompositions:

7 + 8688521 = 8688528
31 + 8688497 = 8688528
59 + 8688469 = 8688528
131 + 8688397 = 8688528
179 + 8688349 = 8688528
229 + 8688299 = 8688528
241 + 8688287 = 8688528
257 + 8688271 = 8688528

Showing the first eight; more decompositions exist.
