As you very well know, this year's funkiest numbers are so called triangular numbers (that is, integers that are representable as
, where $*k*$ is some positive integer), and the coolest numbers are those that are representable as a sum of two triangular numbers.
A well-known hipster Andrew adores everything funky and cool but unfortunately, he isn't good at maths. Given number $*n*$, help him define whether this number can be represented by a sum of two triangular numbers (not necessarily different)!
Input
The first input line contains an integer $*n*$ ($1 ≤ *n* ≤ 10^{9})$.
Output
Print "YES" (without the quotes), if $*n*$ can be represented as a sum of two triangular numbers, otherwise print "NO" (without the quotes).
Note
In the first sample number
.
In the second sample number $512$ can not be represented as a sum of two triangular numbers.
