    In a bank's transaction monitoring system, write a function that identifies potentially coordinated suspicious transactions by counting pairs of transaction amounts whose XOR operation results in an even number. Given a list of transaction amounts as integers, determine how many pairs of transactions exhibit this specific pattern that could indicate related suspicious activities.
