Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697880, here are decompositions:

11 + 8697869 = 8697880
29 + 8697851 = 8697880
47 + 8697833 = 8697880
71 + 8697809 = 8697880
83 + 8697797 = 8697880
89 + 8697791 = 8697880
101 + 8697779 = 8697880
173 + 8697707 = 8697880

Showing the first eight; more decompositions exist.
