I want to recover this long value, that was mistakenly converted to int
long longValue = 11816271602;
int intValue = (int)longValue; // gives -1068630286
long ActualLong = ?
Right shift 32 bits of (intValue >> 32) gives incorrect result.

Well, the initial value
long longValue = 11816271602L; // 0x02C04DFEF2
is five bytes long. When you cast the value to Int32 which is four bytes long
int intValue = (int)longValue; // 0xC04DFEF2 (note 1st byte 02 absence)
you inevitably lose the 1st byte and can't restore it back.

Unfortunately this is not possible. If you take a look at the binary representation you can see the reason:
10 1100 0000 0100 1101 1111 1110 1111 0010
As you can see, this number has 34-bit and not only 32-bit.
