Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628170, here are decompositions:

13 + 8628157 = 8628170
73 + 8628097 = 8628170
139 + 8628031 = 8628170
151 + 8628019 = 8628170
163 + 8628007 = 8628170
193 + 8627977 = 8628170
223 + 8627947 = 8628170
277 + 8627893 = 8628170

Showing the first eight; more decompositions exist.
