Question

{2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, . . .}
40. Show that Goldbach’s Conjecture (see page 5) is true for the even numbers
from 20 to 40 by writing each even number as a sum of two primes

Answer 1

that is 10 numbers, so there are a lot of sums to do, but you want to break each number into a sum of two primes. for example, take 24.
24 = 13+11
13 and 11 are both prime (have no factors). A good tip for finding a sum is to start around half the number and work your way out. e.g. for 24, start at 12, and look at the primes on either side of it- 11 and 13 in this case.
