Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97840, here are decompositions:
- 11 + 97829 = 97840
- 53 + 97787 = 97840
- 167 + 97673 = 97840
- 191 + 97649 = 97840
- 227 + 97613 = 97840
- 233 + 97607 = 97840
- 257 + 97583 = 97840
- 263 + 97577 = 97840
Showing the first eight; more decompositions exist.
