Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641284, here are decompositions:

11 + 8641273 = 8641284
37 + 8641247 = 8641284
53 + 8641231 = 8641284
73 + 8641211 = 8641284
97 + 8641187 = 8641284
137 + 8641147 = 8641284
151 + 8641133 = 8641284
191 + 8641093 = 8641284

Showing the first eight; more decompositions exist.
