var batches = list.Batch(2);

    Console.WriteLine(string.Join(",", batch));

-->

1,2
4,8
10,-4
3

Task[] tasks = batches.Select(batch => Task.Factory.StartNew(() => ExecuteBatch(batch))).ToArray();
Task.WaitAll(tasks);

or

Action[] executions = batches.Select(batch => new Action(() => ExecuteBatch(batch))).ToArray();
var options = new ParallelOptions …
