Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641396, here are decompositions:

47 + 8641349 = 8641396
107 + 8641289 = 8641396
149 + 8641247 = 8641396
263 + 8641133 = 8641396
317 + 8641079 = 8641396
389 + 8641007 = 8641396
419 + 8640977 = 8641396
509 + 8640887 = 8641396

Showing the first eight; more decompositions exist.
