pg(215), pg(69660), pg(92020) and pg(541456) are prp with 215, 69660, 92020, 541456 multiple of 43

pg(215) has 130 digits
pg(69660) has 41940 digits
pg(92020) has 55402 digits
pg(541456) has 325990 digits

so when pg(k) is prp and k multiple of 43

pg(k) has a number of digits multiple of 3 only if k is a multiple of 3.
