Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31736, here are decompositions:
- 7 + 31729 = 31736
- 13 + 31723 = 31736
- 37 + 31699 = 31736
- 73 + 31663 = 31736
- 79 + 31657 = 31736
- 109 + 31627 = 31736
- 163 + 31573 = 31736
- 193 + 31543 = 31736
Showing the first eight; more decompositions exist.
