Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527644, here are decompositions:

11 + 527633 = 527644
17 + 527627 = 527644
41 + 527603 = 527644
53 + 527591 = 527644
137 + 527507 = 527644
191 + 527453 = 527644
197 + 527447 = 527644
233 + 527411 = 527644

Showing the first eight; more decompositions exist.
