Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670160, here are decompositions:

3 + 8670157 = 8670160
53 + 8670107 = 8670160
71 + 8670089 = 8670160
89 + 8670071 = 8670160
131 + 8670029 = 8670160
167 + 8669993 = 8670160
179 + 8669981 = 8670160
197 + 8669963 = 8670160

Showing the first eight; more decompositions exist.
