Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670170, here are decompositions:

13 + 8670157 = 8670170
43 + 8670127 = 8670170
139 + 8670031 = 8670170
163 + 8670007 = 8670170
181 + 8669989 = 8670170
241 + 8669929 = 8670170
277 + 8669893 = 8670170
349 + 8669821 = 8670170

Showing the first eight; more decompositions exist.
