Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8238, here are decompositions:
- 5 + 8233 = 8238
- 7 + 8231 = 8238
- 17 + 8221 = 8238
- 19 + 8219 = 8238
- 29 + 8209 = 8238
- 47 + 8191 = 8238
- 59 + 8179 = 8238
- 67 + 8171 = 8238
Showing the first eight; more decompositions exist.
