My first Leyland prime find

Back in May when I wrote my Indexing the Leyland primes I saw an opportunity to discover some of my own Leyland primes simply by looking where no one else was. My plan was to first check the gaps between the smallest 954 known Leyland primes in order to verify that these gaps contained no additional primes. That process is ongoing. Somewhat bored with the tedium, about a month ago I also started checking some small gaps beyond Leyland prime #954. That search has now borne fruit: 13739^4600 + 4600^13739 is prime!
