Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622170, here are decompositions:

43 + 8622127 = 8622170
163 + 8622007 = 8622170
181 + 8621989 = 8622170
199 + 8621971 = 8622170
211 + 8621959 = 8622170
223 + 8621947 = 8622170
307 + 8621863 = 8622170
313 + 8621857 = 8622170

Showing the first eight; more decompositions exist.
