For the power of natural numbers $m$ greater than or equal to 2, the decomposition formula is as follows:

$2^2 = 1 + 3$  
$3^2 = 1 + 3 + 5$  
$4^2 = 1 + 3 + 5 + 7$  
...  

$2^3 = 3 + 5$  
$3^3 = 7 + 9 + 11$  
...  

$2^4 = 7 + 9$  
...  

According to this pattern, the third number in the decomposition of $5^4$ is $\boxed{125}$.
