Formal mathematics

Reading formal mathematics is even harder than standard theorem / proof mathematics. For example:

$$ \forall{x} \exists{y} (( y \neq 1 \& \forall{z} ( \exists{t} ( z \cdot t = y) \rightarrow ( z=1 \wedge z=y ))) \& \exists{s} (x+s=y)) $$

for all x a y exists such that
    y not equal to 1 and for all  z a t exists such that
       z times t = y implies z =1 or z = y
   and a s exists such that x plus s = y.

Do you get it? There are infinitely many primes.

  1. I don't get it. How can x + s = y implies infinitely many primes?

(Raumpatrouille – Die phantastischen Abenteuer des Raumschiffes Orion, colloquially aka Raumpatrouille Orion was the first German science fiction television series. Its seven episodes were broadcast by ARD beginning September 17, 1966. The series has since acquired cult status in Germany. Broadcast six years before Star Trek first aired in West Germany (in 1972), it became a huge success.)
