Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15982, here are decompositions:
- 11 + 15971 = 15982
- 23 + 15959 = 15982
- 59 + 15923 = 15982
- 101 + 15881 = 15982
- 173 + 15809 = 15982
- 179 + 15803 = 15982
- 191 + 15791 = 15982
- 233 + 15749 = 15982
Showing the first eight; more decompositions exist.
