The number 160 can be obtained purely from prime numbers thus: (23+17+3-19)x(5x5). The result from the first bracket is 24, and from the second is 25, and 24x25 is 600. There are very many ways 600 can be arrived at starting only with prime numbers
No they are not prime numbers because 4 is composite.
4 is not prime.
