Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642310, here are decompositions:

7 + 8642303 = 8642310
29 + 8642281 = 8642310
73 + 8642237 = 8642310
113 + 8642197 = 8642310
137 + 8642173 = 8642310
151 + 8642159 = 8642310
163 + 8642147 = 8642310
191 + 8642119 = 8642310

Showing the first eight; more decompositions exist.
