BGP regular expression help

How would you write the regular expression for the following:

all paths NOT starting with the 1 123 pattern (AS 1 followed by AS 123)

I know that ^1_123 would show me those patterns with 1 123 but I need the
opposite of that (logical not)...

I have tried ^[^1_123] and [^^1_123]

Thanks for guidance...

Kris
