Default The Big Four

I've found the largest four 67-digit numbers with exactly four equally sized prime factors.

In 10^67 - c representation:

Code:
     c               p                   q                   r                   s

The size of my proving file exceeds the 4.00 MB limit for .7z attachments by far.

PS: I do not forget about 10^201 - c.
