Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641300, here are decompositions:

11 + 8641289 = 8641300
53 + 8641247 = 8641300
89 + 8641211 = 8641300
113 + 8641187 = 8641300
167 + 8641133 = 8641300
293 + 8641007 = 8641300
389 + 8640911 = 8641300
587 + 8640713 = 8641300

Showing the first eight; more decompositions exist.
