    Design a fraud detection function that calculates the total sum of all possible transaction split amounts that could make up a given transaction value, where each split amount must evenly divide the total transaction amount. The function should help identify potential structuring patterns where fraudsters break down large transactions into smaller amounts to avoid detection thresholds.
