Better way is to check conditionally in the code. If not possible then use regex at last resort

(?!325([0-2][0-9]|3[0-2])|65535)^[1-5][0-9]{0,4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-4]$

Pattern explanation:

(?!325([0-2][0-9]|3[0-2])|65535)

is used to exclude certain number from the match.

^ and $ is used to match whole string/line from beginning to end.
