Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670208, here are decompositions:

11 + 8670197 = 8670208
17 + 8670191 = 8670208
101 + 8670107 = 8670208
137 + 8670071 = 8670208
167 + 8670041 = 8670208
179 + 8670029 = 8670208
227 + 8669981 = 8670208
269 + 8669939 = 8670208

Showing the first eight; more decompositions exist.
