how to convert keys values map to slice of int : <p>i'm trying to convert key-value map to slice of 2 value, for example :</p>

<pre><code>slices := make(map[int64]int64)
slices[int64(521)] = int64(4)
slices[int64(528)] = int64(8)
// how do i convert that to become
// [[521, 4], [528, 8]]
</code></pre>

<p>i'm thinking about each all those key-value then create slice for that, but is there any simple code to do that ?</p>
