Sorry for still not seeing how to get from the infinite
product of Wallis

pi = 2 x 4/3 x 16/15 x 64/63 x 100/99 x 144/143 ...

to the infinite product of Euler

pi = 2 x 3/2 x 5/6 x 7/6 x 11/10 x 13/14 x 17/18 ...

When I start dividing the product of Wallis and eliminate
the composites I get an endless procession of powers of 2
in the numerator, and primes in the denominator, whereas
Euler has the product of all subsequent primes for the
numerator, and even numbers in the denominator.
