Math Help prove that if n>6 then $\exists a,b \in N \ a,b >1 , \ gcd (a,b)=1$ such that n= a+b Hello, $n > 6$. Consider two cases : $\Rightarrow n$ is odd. Let $a = \frac{n - 1}{2}$ and $b = \frac{n + 1}{2}$. $a + b = \frac{2n}{2} = n$, and $b - a = \frac{n + 1 - n + 1}{2} = 1$. Since $b = a + 1$, $gcd(a, b) = 1$. $\...
