Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641360, here are decompositions:

11 + 8641349 = 8641360
29 + 8641331 = 8641360
41 + 8641319 = 8641360
59 + 8641301 = 8641360
71 + 8641289 = 8641360
113 + 8641247 = 8641360
149 + 8641211 = 8641360
173 + 8641187 = 8641360

Showing the first eight; more decompositions exist.
