Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31670, here are decompositions:
- 3 + 31667 = 31670
- 7 + 31663 = 31670
- 13 + 31657 = 31670
- 43 + 31627 = 31670
- 97 + 31573 = 31670
- 103 + 31567 = 31670
- 127 + 31543 = 31670
- 139 + 31531 = 31670
Showing the first eight; more decompositions exist.
