Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641022, here are decompositions:

73 + 8640949 = 8641022
139 + 8640883 = 8641022
151 + 8640871 = 8641022
163 + 8640859 = 8641022
199 + 8640823 = 8641022
223 + 8640799 = 8641022
241 + 8640781 = 8641022
283 + 8640739 = 8641022

Showing the first eight; more decompositions exist.
