First, take all the even natural numbers greater than 2 (e. g. 4, 6, 8, 10, 12…). Next, take each even number and try to rewrite it as the sum of 2 prime numbers. For our first 5 elements of our list, we get: 4 = 2+2 6 = 3+3 8 = 3+5 10 = 3+7 = 5+5 12 = 7+5 … 100 = 3+97 = 11+89 The question is, can you keep doing this forever?
