Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31850, here are decompositions:
- 3 + 31847 = 31850
- 79 + 31771 = 31850
- 109 + 31741 = 31850
- 127 + 31723 = 31850
- 151 + 31699 = 31850
- 163 + 31687 = 31850
- 193 + 31657 = 31850
- 223 + 31627 = 31850
Showing the first eight; more decompositions exist.
