Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664880, here are decompositions:

11 + 8664869 = 8664880
17 + 8664863 = 8664880
23 + 8664857 = 8664880
89 + 8664791 = 8664880
137 + 8664743 = 8664880
149 + 8664731 = 8664880
179 + 8664701 = 8664880
353 + 8664527 = 8664880

Showing the first eight; more decompositions exist.
