Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718208, here are decompositions:

11 + 8718197 = 8718208
17 + 8718191 = 8718208
197 + 8718011 = 8718208
227 + 8717981 = 8718208
269 + 8717939 = 8718208
281 + 8717927 = 8718208
347 + 8717861 = 8718208
461 + 8717747 = 8718208

Showing the first eight; more decompositions exist.
