 Include 1 as a prime for this problem (blasphemy! ). Show that every integer is the sum of distinct primes.

 This reminds me of another problem. Show that every even integer greater than two can be written as the sum of two primes.
Note that they don't have to be distinct and 1 does not count as a prime in this case.
Kudos to any of you that solve this problem...Let's say it's a bit of a tough one...

What's up Mitch! I haven't seen you in a while! The problem you are giving is quite hard indeed! Here's a plot of the number of representations of each even integer as a sum of two primes. It looks very nice! My problem above is easier, rest assured.
