Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698240, here are decompositions:

11 + 8698229 = 8698240
17 + 8698223 = 8698240
53 + 8698187 = 8698240
107 + 8698133 = 8698240
179 + 8698061 = 8698240
191 + 8698049 = 8698240
263 + 8697977 = 8698240
269 + 8697971 = 8698240

Showing the first eight; more decompositions exist.
