EXAMPLE

a(1) = A030461(1) = 23. gap = 3 - 2 = 1.

a(2) = 3137, because 3137 is the first term in A030461 > 23, with gap = 37 - 31 = 6 > 1.

a(3) = 199211, because 199211 is the first term in A030461 > 3137, with gap = 211 - 199 = 12 > 6.

MATHEMATICA

Reap[For[record = 0; p = 2, p < 10^8, p = NextPrime[p], If[PrimeQ[pp = FromDigits[Join[IntegerDigits[p], IntegerDigits[np = NextPrime[p]]]]], If[np - p > record, record = np - p; Print[pp]; Sow[pp]]]]][[2, 1]] (* Jean-Fran├žois Alcover, Mar 02 2016 *)
