Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 535640, here are decompositions:

3 + 535637 = 535640
13 + 535627 = 535640
31 + 535609 = 535640
67 + 535573 = 535640
151 + 535489 = 535640
241 + 535399 = 535640
307 + 535333 = 535640
337 + 535303 = 535640

Showing the first eight; more decompositions exist.
