I think this is a duplicate of bug #45945.

Octave's int64 variables are stored as 64-bit integers, not doubles. The problem is with parsing large integer constants and converting them all to double.

but:
The latter numbers should all be even, right?
I suspect, Octave's int64 are double with only 53 digit mantissa.
