Sažetak

Let \(m>31\) be an even integer with \(\gcd(m,31)=1\). In this paper, using some elementary methods, we prove that the equation \((m^2-31^2)^x+(62m)^y=(m^2+31^2)^z\) has only the positive integer solution \((x,y,z)=(2,2,2)\). This result resolves an open problem raised by T. Miyazaki ({\em Acta Arith.} 186 (2018), 1--36) about Je\'smanowicz' conjecture concerning primitive Pythagorean triples.
