Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97870, here are decompositions:
- 11 + 97859 = 97870
- 23 + 97847 = 97870
- 29 + 97841 = 97870
- 41 + 97829 = 97870
- 83 + 97787 = 97870
- 197 + 97673 = 97870
- 257 + 97613 = 97870
- 263 + 97607 = 97870
Showing the first eight; more decompositions exist.
