Serial.print two EEPROM values

Using Arduino Programming Questions
#1

I want the following code (a function) to print something like this:

1 = 2
4 = 2
1 = 3
5 = 6

  void printKey() {
    
    Serial.println(EEPROM.read(1) & " = " & EEPROM.read(5));
    Serial.println(EEPROM.read(2) & " = " & EEPROM.read(6));
    Serial.println(EEPROM.read(3) & " = " & EEPROM.read(7));
    Serial.println(EEPROM.read(4) & " = " & EEPROM.read(8));
    
  }

However, it is not working. If I do it like this:

  void printKey() {
    
    Serial.println(EEPROM.read(1) + " = " + EEPROM.read(5));
    Serial.println(EEPROM.read(2) + " = " +  EEPROM.read(6));
    Serial.println(EEPROM.read(3) + " = " +  EEPROM.read(7));
    Serial.println(EEPROM.read(4) + " = " + EEPROM.read(8));
    
  }

It somehow grabs other Serial text and scrambles it. Whats going on and how can I make it do this:

1 = 2
4 = 2
1 = 3
5 = 6

Thanks!

Split it into separate prints:

void printKey() {
    Serial.print(EEPROM.read(1)); Serial.print(" = "); Serial.println(EEPROM.read(5));
    Serial.print(EEPROM.read(2)); Serial.print(" = "); Serial.println(EEPROM.read(6));
    Serial.print(EEPROM.read(3)); Serial.print(" = "); Serial.println(EEPROM.read(7));
    Serial.print(EEPROM.read(4)); Serial.print(" = "); Serial.println(EEPROM.read(8));
}
