or, "718347 19734307611107 718311437197 43234311"

The code is a simple substitution code created by substituting the letter series into the series of prime numbers. The letters are:

a	02
b	03
c	05
d	07
e	11
f	13
g	17
h	19
i	23
j	29
k	31
l	37
m	41
n	43
o	47
p	53
q	59
r	61
s	67
t	71
u	73
v	79
w	83
x	89
y	97
z	101
Here's how the question works out:
83 19 02 71   23 67   71 19 11   13 23 13 71 23 11 71 19
W  H  A  T    I  S    T  H  E    F  I  F  T  I  E  T  H

53 61 23 41 11   43 73 41 03 11 61 ?
P  R  I  M  E    N  U  M  B  E  R  ?
And the answer:
71 83 47   19 73 43 07 61 11 07  71 83 11 43 71 97  43 23 43 11
