Reorganize numbers

Given an array of positive integers, your task is to reorganize the array so that all even numbers appear before the odd numbers.
The order of the numbers doesn't need to be preserved - as long as all evens show up first.
For example, given the input
[3, 5, 2, 1, 9, 8, 6, 7]
Your function should return:
[2, 8, 6, 3, 5, 1, 9, 7]
Use multiple pointers and solve this in place.
