EXAMPLE

a[0]=1751793 because there are no primes between 210*1751793 and 210*1751794.

a[1]=235449 because there is one prime between 210*235449 and 210*235450.

MATHEMATICA

ta=Table[0, {up}]; Do[{m=0}; Do[s=210*k+r; s1=210*k+r+2; If[PrimeQ[s], m=m+1], {r, 1, 210}]; ta[[k]]=m, {k, 1, up}] Table[Min[Flatten[Position[ta, j]]], {j, 1, 48}]
