... equal to 4, and all such integers are composite. Then n = 8 + (n − 8) expresses n as the sum of the composite numbers 8 and n − 8. n is odd. Then n ≥ 13 > 9. In this case, n − 9 is a positive, even integer greater than or equal to 4, and n = 9 + (n − 9) expresses n as the sum of the composite number ...
