Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3238, here are decompositions:
- 17 + 3221 = 3238
- 29 + 3209 = 3238
- 47 + 3191 = 3238
- 71 + 3167 = 3238
- 101 + 3137 = 3238
- 149 + 3089 = 3238
- 197 + 3041 = 3238
- 227 + 3011 = 3238
Showing the first eight; more decompositions exist.
