Oh, come on. There are at least 3 well known constructive 
proofs that all odd numbers are prime:

The mathematician's:
 3 is prime,
 5 is prime,
 7 is prime
 as so on, by induction.

The physicist's:
 3 is prime,
 5 is prime,
 7 is prime,
 9 is prime <experimental error>
 11 is prime...

The computer scientist's:
 3 is prime,
 3 is prime,
 3 is prime ....
