input: Write a python function to find pairs of odd numbers that sum up to each even number in a list.
  assert sumOfOdds([4, 6, 10, 8]) == [[1, 3], [1, 5], [1, 9], [1, 7]]
  assert sumOfOdds([2, 14, 18]) == [[1, 13], [1, 17]]
  assert sumOfOdds([12, 20, 22]) == [[1, 11], [1, 19], [1, 21]]
output: def sumOfOdds(even_numbers):
      def find_pairs(n):
          pairs = []
          for i in range(1, n//2 + 1, 2):
              pairs.append([i, n - i])
          return pairs
      
      result = []
      for num in even_numbers:
          if num % 2 == 0:
              result.extend(find_pairs(num))
      return result
