This is a 5,547-digit Titanic twin-prime midpoint MP, where MP − 1 and MP + 1 are both probable primes. It is also the lower twin-prime midpoint in my largest currently found Martini quartet. With k = 652598 and prime gap = 5851414, the satellite pair MP × 652598 ± 2925707 is also probable prime on both sides. The four probable primes are therefore: MP − 1, MP + 1, MP × 652598 − 2925707, and MP × 652598 + 2925707. All four have been tested PRP base 2 and base 3 with pfgw64. [Maughan]
