To find the integer that makes the addition sentence true, we need to solve for the unknown integer (let’s call it \( x \)) in the equation:
\[ x + 454 = 892 \]
Subtract 454 from both sides:
\[ x = 892 - 454 \]
Now, calculate \( 892 - 454 \):
\[ 892 - 454 = 438 \]
Thus, the integer that makes the addition sentence true is:
\[ \boxed{438} \]
