Goldbach revisited (Posted on 2010-06-12) Difficulty: 2 of 5
 The Goldbach Conjecture states that every even number greater than 2 can be expressed as a sum of two primes.
  For example, 4=2+2 and 16 = 5 + 11. 
What is the smallest number for which there are 5 different ways to express this number as a sum of two primes?

48 = 5 + 43 = 7 + 41 = 11 + 37 = 17 + 31 = 19 + 29
