# Fun with Prime Numbers

## Recommended Posts

Some dude a very long time ago told me that every even number can be expressed as the sum of two different prime numbers...

Let's test that!

Starting with 10 and moving on...

10 = 7 + 3

12 = 7 + 5

14 = 11 + 3

16 = 11 + 5

18 = 11 + 7

20 = 13 + 7

22 = 17 + 5

You get the idea?

Let's go!

24=13+11

26=13+13

28=17+11

30=17+13

Like this? ##### Share on other sites

YES! Like that. This is my bad because I didn't indicate that the two prime numbers had to be different but 26 should be 23 + 3.

Isn't this fun?

32 = 27 + 5

34 = 27 + 7

36 = 19 + 17

38 = 31 + 7

40 = 29 + 11

42 = 31 + 11

44 = 37 + 7

46 = 41 + 5

^^You made a mistake in the last calculation

224 = 211 + 13

226 = 173 + 53

228 = 223 + 5

230 = 127 + 103

232 = 59 + 173

234 = 83 + 151

236 = 223 + 13

238 = 197 + 41

240 = 229 + 11

242 = 199 + 43

246 = 233 + 13

248 = 151 + 97

250 = 239 + 11

252 = 113 + 139

OMG i see I corrected it ##### Share on other sites

Some of numbers you used are not primes.
