Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639260, here are decompositions:

11 + 8639249 = 8639260
41 + 8639219 = 8639260
53 + 8639207 = 8639260
83 + 8639177 = 8639260
89 + 8639171 = 8639260
107 + 8639153 = 8639260
137 + 8639123 = 8639260
197 + 8639063 = 8639260

Showing the first eight; more decompositions exist.
