      is the third in an arithmetic progression of primes.

      Sascha Dinkel used LLR to prove the primality of
      A = 1185*2^529444 + 1

      Steven Harvey used OpenPFGW to prove the primality of
      B = 1539*2^263359 + 1
      http://primes.utm.edu/primes/page.php?id=78158
      and I used OpenPFGW to prove the primality of
      N = 2*A - B, at 159382 decimal digits:
      Running N-1 test using base 11
      Calling Brillhart-Lehmer-Selfridge with factored part 49.74%
      1185*2^529445-1539*2^263359+1 is prime! (4000.3667s+0.0063s)
