Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38458, here are decompositions:
- 5 + 38453 = 38458
- 11 + 38447 = 38458
- 107 + 38351 = 38458
- 131 + 38327 = 38458
- 137 + 38321 = 38458
- 197 + 38261 = 38458
- 227 + 38231 = 38458
- 239 + 38219 = 38458
Showing the first eight; more decompositions exist.
