Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715808, here are decompositions:

29 + 8715779 = 8715808
47 + 8715761 = 8715808
89 + 8715719 = 8715808
137 + 8715671 = 8715808
149 + 8715659 = 8715808
191 + 8715617 = 8715808
359 + 8715449 = 8715808
461 + 8715347 = 8715808

Showing the first eight; more decompositions exist.
