Matthew Parker's Decoder #2017-01

Did you have a tough time cracking January’s stopwatch code? Here it is again:

Matthew's Decoder #2017-01

How It Works

First, multiply the minutes by 60 and add the remaining seconds to convert stopwatch times to total seconds: 179, 2, 151, 5 and 41.

This code uses additive primes—prime numbers whose digits add up to another prime number. For example, 83 is a number that can only be divided by 1 or itself, and so is 11 (8 + 3). That makes 83 an additive prime.

Substitute the total seconds on each watch for a letter using the additive primes table below.
