Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31940, here are decompositions:
- 67 + 31873 = 31940
- 199 + 31741 = 31940
- 211 + 31729 = 31940
- 241 + 31699 = 31940
- 277 + 31663 = 31940
- 283 + 31657 = 31940
- 313 + 31627 = 31940
- 367 + 31573 = 31940
Showing the first eight; more decompositions exist.
