I also have a record size pair over 40k digits I found with Paul Jobling a few years ago which was sent to Jan but never processed.
Sometime I'll dig it out and test both pages with it!!!

I haven't set up a mail server yet. I can however build a file with just the new pairs when processing a submission and then give a download link to it. Actually, it's a good idea - to log all submissions this way. I'll try it this evening. My scripts should handle 40,000 digit numbers, _if_ they don't exceed execution time limit.

New record even-even pair with smallest known m/n ratio found:
Code:
X73 Chernykh 2015
523445399739689350=2*5^2*7*11*17*31*37*73*191*500083
865023542517044858=2*31*37*107*63487*55509323
The ratio is ~0.60512272, previous record ratio was ~0.6468 for the pair (35049418250,54192685558)

I've just added the record pair I mentioned, it took a few days to recover it as I had a record
of the input that produced it but not of the actual pair!

The pair has been submitted to both databases

It's 43145 digits.

Congratulations! My database automatically marked it as discovered in 2015, but if you remember when it was actually found, I can fix it.

It was back in 2011. (26 September just for the record. The primes were also checked using PFGW with p-1 or p+1 tests which give a 100% verification)
