Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641366, here are decompositions:

5 + 8641361 = 8641366
17 + 8641349 = 8641366
47 + 8641319 = 8641366
179 + 8641187 = 8641366
233 + 8641133 = 8641366
269 + 8641097 = 8641366
359 + 8641007 = 8641366
389 + 8640977 = 8641366

Showing the first eight; more decompositions exist.
