there are 6 prime numbers of the form 10n+3.
if n = 1, number = 13 (prime)
if n = 2, number= 23 (prime)
if n = 3, number = 33 (composite)
if n = 4, number = 43 (prime)
if n = 5, number = 53 (prime)
if n = 6, number = 63 (composite)
if n = 7, number = 73 (prime)
if n = 8, number = 83 (prime)
if n = 9, number = 93 (composite)
So, in total six numbers.
