Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38188, here are decompositions:
- 5 + 38183 = 38188
- 11 + 38177 = 38188
- 149 + 38039 = 38188
- 191 + 37997 = 38188
- 197 + 37991 = 38188
- 281 + 37907 = 38188
- 317 + 37871 = 38188
- 389 + 37799 = 38188
Showing the first eight; more decompositions exist.
