Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628164, here are decompositions:

3 + 8628161 = 8628164
7 + 8628157 = 8628164
43 + 8628121 = 8628164
67 + 8628097 = 8628164
157 + 8628007 = 8628164
211 + 8627953 = 8628164
271 + 8627893 = 8628164
313 + 8627851 = 8628164

Showing the first eight; more decompositions exist.
