All Prime Numbers Greater than 3 Could be Written as 1 + Multiplying of More than 2 Prime Numbers but vice versa is Not True

Mohammadreza Barghi

Abstract: According to definition, prime numbers can?t be written as multiplying of any whole numbers (whole numbers that are greater than 1) but we can write prime numbers that are greater than 3 as: 1 + multiplying of two or more prime numbers. Vice versa of this issue is not true i.e. not all numbers that produced by adding 1 to multiplying of some prime numbers are prime numbers.
