Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641266, here are decompositions:

17 + 8641249 = 8641266
19 + 8641247 = 8641266
79 + 8641187 = 8641266
173 + 8641093 = 8641266
317 + 8640949 = 8641266
379 + 8640887 = 8641266
383 + 8640883 = 8641266
443 + 8640823 = 8641266

Showing the first eight; more decompositions exist.
