2779^1632+1632^2779
2779^2560+2560^2779

Thank you Rich.

Several more Primo proofs:

2495^2424+2424^2495
2528^2031+2031^2528
2553^974+974^2553
2573^1134+1134^2573

Yet a few more Primo proofs.
I believe this completes all PRPs where x<2800.

2448^535+535^2448
2453^2094+2094^2453
2460^671+671^2460
2463^1274+1274^2463
2470^1249+1249^2470
2473^1188+1188^2473
2481^2432+2432^2481
2489^1858+1858^2489
2494^635+635^2494
2522^537+537^2522
2543^414+414^2453
2675^298+298^2675

A few more Primo proofs.
This should complete all PRPs where x<3000.

2803^916+916^2803
2823^836+836^2823
2826^1289+1289^2826
2831^666+666^2831
2843^208+208^2843
2883^1136+1136^2883
2890^1671+1671^2890
2892^2035+2035^2892
2974^2735+2735^2974
2987^2680+2680^2987
2996^1563+1563^2996

It's been a while since I've seen a primality proof of a Leyland number here, so to rectify that, earlier today I did the proof of 214^3147+3147^214: http://factordb.com/index.php?id=1100000000420123164

Whoops, I just saw this thread here. If wished for, would you please move my posts with the proof reservations from the other thread here?

All Leyland primes below 10,000 digits are now certified in FactorDB; my reservations are completed. For now, I will not reserve anything new.

When I just checked Prime Wiki, there were still three numbers below 10,000 digits that have no certificate on FactorDB. I must have overlooked them, I guess? I will rectify this omission soon. Also, I will add certificates for the next three numbers that do not have a certificate yet after that. For the next year, my goal is to have all up to 12,500 digits certified. Any help for this endeavour is appreciated. But beside the six numbers mentioned above, it will be some time until I start this.
