Constant pattern primes
Thank you for your comments and contributions. First I am not academic mathematical. I am fond mathematical. But I'm working on a consecutive pattern of prime numbers. I go crazy for them. I'm still working on this pattern even that everyone says does not exist. Any suggestions for this newbie?

http://pari.math.ubordeaux.fr/ or even do it by hand  this would take 40 modular multiplications (28 of them squaring, which is actually easier) by the usual method, not particularly fast but doable.

Can you explain what you wish to accomplish by testing this number with Prime95?
If English isn't your first language, maybe you could even write an explanation in your language and someone on this board might be able to understand and translate it. Is 281414479 the only number you are interested in, or is there perhaps a list that includes a few other numbers? If so, you could post the list of numbers and then we could suggest another number from the list that might be more useful for the goals of this project.
