Goldbach revisited (Posted on 2010-06-12)

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?

The required minimum number is 48, since:

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