Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670222, here are decompositions:

31 + 8670191 = 8670222
151 + 8670071 = 8670222
181 + 8670041 = 8670222
191 + 8670031 = 8670222
193 + 8670029 = 8670222
229 + 8669993 = 8670222
233 + 8669989 = 8670222
241 + 8669981 = 8670222

Showing the first eight; more decompositions exist.
