The question provided involves solving the quadratic equation \( x^2 - 10x + 2 = 0 \) by completing the square and expressing the solutions in the form \( a \pm \sqrt{b} \), where \( a \) and \( b \) are prime numbers.

### Step-by-Step Solution:

1. **Rewrite the equation**:
   \[
   x^2 - 10x + 2 = 0
   \]

2. **Move the constant to the other side**:
   \[
   x^2 - 10x = -2
   \]

3. **Complete the square**:
   To complete the square, take half the coefficient of \( x \), square it, and add it to both sides. The coefficient of \( x \) is \( -10 \), so:
   \[
   \left( \frac{-10}{2} \right)^2 = 25
   \]
   Add 25 to both sides:
   \[
   x^2 - 10x + 25 = -2 + 25
   \]
   Simplifies to:
   \[
   (x - 5)^2 = 23
   \]

4. **Solve for \( x \)**:
   Take the square root of both sides:
   \[
   x - 5 = \pm \sqrt{23}
   \]
   Therefore:
   \[
   x = 5 \pm \sqrt{23}
   \]

5. **Interpret the solution**:
   The solutions are \( x = 5 \pm \sqrt{23} \), which can be written in the form \( a \pm \sqrt{b} \) where \( a = 5 \) and \( b = 23 \).

Since \( 5 \) and \( 23 \) are both prime numbers, this satisfies the condition.

### Final Answer:
- \( a = 5 \)
- \( b = 23 \)
