Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31782, here are decompositions:
- 11 + 31771 = 31782
- 13 + 31769 = 31782
- 31 + 31751 = 31782
- 41 + 31741 = 31782
- 53 + 31729 = 31782
- 59 + 31723 = 31782
- 61 + 31721 = 31782
- 83 + 31699 = 31782
Showing the first eight; more decompositions exist.
