Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641258, here are decompositions:

11 + 8641247 = 8641258
47 + 8641211 = 8641258
71 + 8641187 = 8641258
179 + 8641079 = 8641258
251 + 8641007 = 8641258
281 + 8640977 = 8641258
347 + 8640911 = 8641258
491 + 8640767 = 8641258

Showing the first eight; more decompositions exist.
