Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641064, here are decompositions:

97 + 8640967 = 8641064
181 + 8640883 = 8641064
193 + 8640871 = 8641064
241 + 8640823 = 8641064
277 + 8640787 = 8641064
283 + 8640781 = 8641064
331 + 8640733 = 8641064
373 + 8640691 = 8641064

Showing the first eight; more decompositions exist.
