2, 11 and 31, are prime and, when added together, make 44.
17 and 19
Look at the first 2 of these prime numbers. They cannot be even for then they would be divisible by 2, so not prime. Add them together. Two odd numbers added together make an even. Subtract this even number from 50 (also even) so the third number must be even. There is no way of adding 3 prime numbers together to make an even number.
59 + 7 = 66. hope this helped, definitely worked for my homework. Jasmin aged 11
