Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39982, here are decompositions:
- 3 + 39979 = 39982
- 11 + 39971 = 39982
- 29 + 39953 = 39982
- 53 + 39929 = 39982
- 113 + 39869 = 39982
- 191 + 39791 = 39982
- 233 + 39749 = 39982
- 263 + 39719 = 39982
Showing the first eight; more decompositions exist.
