%N Primes which are sum of the first k consecutive composite numbers and such that the sums of the first k+1, k+2 and k+3 consecutive composites are also prime.
%C Since there are not 3 consecutive twin primes, with the exception of (3, 5, 7) because one of them would be divisible by 3; there cannot be primes sum of the first consecutive k composites, and such that the sums of the first k+1, k+2, k+3, and k+4 consecutive composites are also prime.
%e a(1) = 1041973527756883 is the least prime, sum of the first consecutive 44208182 composites from 4 to 47042265, and such that the sum of the first 44208183, 44208184 and 44208185 composites are 1041973574799149, 1041973621841417, 1041973668883687, all prime.
