I am thinking of a five-digit number such that:
The first and last digits are the same, their submission is an even number and multiplication is an odd number and is equal to the fourth number. Subtract five from it and we obtain the second number. Then divide into exact halves and we get the 3rd number.

What number I am thinking of?

It lies behind stars and under hills, And empty holes it fills.
It comes first and follows after, Ends life, and kills laughter.
