Rivera conjectures that this sequence is finite. - Rivera
Rivera's conjecture that this sequence is finite conflicts with heuristics; the next entry is almost certainly 6205, since Floor[(Pi-3)*10^6205] is (very) probably prime, though its proof may take decades - David Broadhurst, Nov 08 2000
Floor[(Pi-3)*10^6205] is a strong pseudoprime to all (1229) prime bases a < 10000 (the test took 45 minutes) - Joerg Arndt, Jan 16 2011.
