In 1742 the mathematician Christian Goldbach observed that every even number (except 2) seemed representable as the sum of two primes. Goldbach could not prove this result, known today as Goldbach's conjecture, so he wrote to his friend, the world-famous mathematician Leonhard Euler. Euler was unable to prove or disprove this conjecture, and it remains unsolved to this day. Write the numbers 16, 18, 20 as the sum of two primes. ?
A. 16 = 3 + 13, 18 = 1 + 17, 20 = 5 + 15 B. 16 = 13 + 3, 18 = 15 + 3, 20 = 16 + 4 C. 16 = 14 + 2, 18 = 13 + 5, 20 = 15 + 5 D. 16 = 13 + 3, 18 = 13 + 5, 20 = 13 + 7 E. 16 = 11 + 5, 18 = 11 + 7, 20 = 1 + 19
