Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670880, here are decompositions:

11 + 8670869 = 8670880
17 + 8670863 = 8670880
89 + 8670791 = 8670880
107 + 8670773 = 8670880
137 + 8670743 = 8670880
167 + 8670713 = 8670880
227 + 8670653 = 8670880
269 + 8670611 = 8670880

Showing the first eight; more decompositions exist.
