Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38540, here are decompositions:
- 79 + 38461 = 38540
- 109 + 38431 = 38540
- 163 + 38377 = 38540
- 211 + 38329 = 38540
- 223 + 38317 = 38540
- 241 + 38299 = 38540
- 373 + 38167 = 38540
- 421 + 38119 = 38540
Showing the first eight; more decompositions exist.
