Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688858, here are decompositions:

29 + 8688829 = 8688858
41 + 8688817 = 8688858
67 + 8688791 = 8688858
71 + 8688787 = 8688858
151 + 8688707 = 8688858
229 + 8688629 = 8688858
251 + 8688607 = 8688858
257 + 8688601 = 8688858

Showing the first eight; more decompositions exist.
