Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625164, here are decompositions:

43 + 8625121 = 8625164
73 + 8625091 = 8625164
151 + 8625013 = 8625164
157 + 8625007 = 8625164
211 + 8624953 = 8625164
277 + 8624887 = 8625164
283 + 8624881 = 8625164
487 + 8624677 = 8625164

Showing the first eight; more decompositions exist.
