Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27982, here are decompositions:
- 29 + 27953 = 27982
- 41 + 27941 = 27982
- 89 + 27893 = 27982
- 131 + 27851 = 27982
- 173 + 27809 = 27982
- 179 + 27803 = 27982
- 191 + 27791 = 27982
- 233 + 27749 = 27982
Showing the first eight; more decompositions exist.
