CHG proof at 32993 digits and 26.46% factorization with details in http://physics.open.ac.uk/~dbroadhu/cert/b16200b.zip and a certificate compressed to 13 MB in http://physics.open.ac.uk/~dbroadhu/cert/b16200b_cert.gp.gz

Verification data:

The Top 5000 Primes is a list for proven primes only. In order to maintain the integrity of this list, we seek to verify the primality of all submissions.  We are currently unable to check all proofs (ECPP, KP, ...), but we will at least trial divide and PRP check every entry before it is included in the list.
