Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38198, here are decompositions:
- 31 + 38167 = 38198
- 79 + 38119 = 38198
- 151 + 38047 = 38198
- 211 + 37987 = 38198
- 241 + 37957 = 38198
- 337 + 37861 = 38198
- 367 + 37831 = 38198
- 499 + 37699 = 38198
Showing the first eight; more decompositions exist.
