Yes, you need to use all prime numbers. Generally, if y=x*z, then there is no integer w such that y+1=x*w. In that case, you could substitute y in the second equation and get
y+1=x*z+1=x*w
x*(z-w)=-1
x=1/(w-z)
so the only set of integers this would work with requires x=+-1 if w and z are 1...

Almost 10k pages long, and there has yet to be a chapter that makes me want to stop reading. At most, I've delayed reading a chapter afew hours because I have work to do.
Strangers complement my voice when I speak, which is ironic, because I hate hearing it. Part of that might be because I have asthma, so even speaking can be tiresome, but mostly because it sounds too deep, which doesn't jive with my self-image.
Technically, it's PrePure, which is legally distinct from PreCure, in such a way that they can make up what happens in the show without risking being sued for misusing intellectual property or something. So I say no, not fanfiction.
