Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641270, here are decompositions:

23 + 8641247 = 8641270
59 + 8641211 = 8641270
83 + 8641187 = 8641270
137 + 8641133 = 8641270
173 + 8641097 = 8641270
191 + 8641079 = 8641270
263 + 8641007 = 8641270
293 + 8640977 = 8641270

Showing the first eight; more decompositions exist.
