EXAMPLE

The first two primes of the form 10k + 3 are 3 and 13, so a(1)=13. The next prime of this form is 23; the gap 2313 is not a record so nothing is added to the sequence. The next prime of this form is 43 and the gap 4323=20 is a new record, so a(2)=43.


PROG

(PARI) re=0; s=3; forprime(p=13, 1e8, if(p%10!=3, next); g=ps; if(g>re, re=g; print1(p", ")); s=p)
