## Description
<section id='description'>

It is possible to write ten as the sum of primes in exactly five different ways:

<div style='margin-left: 4em;'>
  7 + 3<br>
  5 + 5<br>
  5 + 3 + 2<br>
  3 + 3 + 2 + 2<br>
  2 + 2 + 2 + 2 + 2<br>
</div>

What is the first value which can be written as the sum of primes in over five thousand different ways?
