Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670220, here are decompositions:

23 + 8670197 = 8670220
29 + 8670191 = 8670220
113 + 8670107 = 8670220
131 + 8670089 = 8670220
149 + 8670071 = 8670220
179 + 8670041 = 8670220
191 + 8670029 = 8670220
227 + 8669993 = 8670220

Showing the first eight; more decompositions exist.
