COMMENTS

Because 3digit terms coincide with additive 3dimensional primes A046713, it is interesting to start with 4digit primes. All of them may use only zero and odd digits, with the unique exclusion 2003 with one even digit. Primes such that sum of any two_neighbor_digits is prime A086244.

EXAMPLE

1973 is a term because 1+9+7=17, 9+7+3=19, 7+3+1=11 and 3+1+9=13 are all prime.
