Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641294, here are decompositions:

5 + 8641289 = 8641294
47 + 8641247 = 8641294
83 + 8641211 = 8641294
107 + 8641187 = 8641294
197 + 8641097 = 8641294
317 + 8640977 = 8641294
383 + 8640911 = 8641294
587 + 8640707 = 8641294

Showing the first eight; more decompositions exist.
