".......I must have taken too long because it logged me out!"
When you logged on did you tick the check "Remember me"?

That was not my solution set. 

Interestingly however that if I use one half of my solution with one half of yours I do arrive at another satisfactory result.  I initially thought that I had arrived at another successful solution by combining our other halves, unfortunately one of the primes was duplicated.
