Question on Flowchart (Prime Number)

[4wCjE3v7]

Draw a flowchart to display all the prime numbers below a given number.
e.g. Input is 10, output : 2,3,5,7

Here's my flowchart:

By right, is the flowchart acceptable? I'm wondering if my input is 2, will it output 2 also?

Thanks for your guides!

Did you try tracing this through by hand? What were the results?

I started off trying to follow it myself, but wasn't sure that I was correctly reading the hand-written text so I stopped.
