Which two numbers should be interchanged to make the given equation correct?

74 – 52 + (39 ÷ 13) × 16 + (14 ÷ 2) = 106

(NOTE: Numbers must be interchanged and not the constituent digits e.g. if 2 and 3 are to be interchanged in the equation 43 × 3 + 4 ÷ 2, then interchanged equation is 43 × 2 + 4 ÷ 3)
