Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9982, here are decompositions:
- 41 + 9941 = 9982
- 53 + 9929 = 9982
- 59 + 9923 = 9982
- 131 + 9851 = 9982
- 149 + 9833 = 9982
- 179 + 9803 = 9982
- 191 + 9791 = 9982
- 233 + 9749 = 9982
Showing the first eight; more decompositions exist.
