Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641306, here are decompositions:

5 + 8641301 = 8641306
17 + 8641289 = 8641306
59 + 8641247 = 8641306
173 + 8641133 = 8641306
227 + 8641079 = 8641306
419 + 8640887 = 8641306
587 + 8640719 = 8641306
593 + 8640713 = 8641306

Showing the first eight; more decompositions exist.
