How to split a public key into 2 parts of less complexity?

Question

Cryptography

Have a nice day.

Tell me, what manipulations should be done with the bitcoin public key in order to divide it into 2 parts of less complexity or reduce the complexity inherent in the public key in a different way (not by dividing into 2 parts)?

Here is an example of a public key:

0465ec2994b8cc0a20d40dd69edfe55ca32a54bcbbaa6b0ddcff36049301a545795a1b76ab01e9edd0de24157ceff77bcb0f615560b250b365a5d435873eaa4625

The formula for the public key is P=xQ where x is the private key and Q is the base point.
The public key contains the X, Y coordinates of a point on an elliptic curve.

Answer 1

and then each part for two more?
recursively?
only a wired key can handle a bitcoin key (c)
