47 + 3 = 50, 43 + 7 = 50, 37 + 13 = 50, and 31 + 19 = 50. 4 pairs of prime numbers have a sum of 50. 53 + 7 = 60, 47 + 13 = 60, 43 + 17 = 60, 41 + 19 = 60, 37 + 23 = 60, and 31 + 29 = 60. 6 pairs of prime numbers have a sum of 60.
The sum of the numbers 1 to 39 = 39 x 40 ÷ 2 = 780 The sum of the numbers 1 to 60 = 60 x 61 ÷ 2 = 1830 Therefore the sum of the numbers 40 to 60 = 1830 - 780 = 1050
