Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47986, here are decompositions:
- 5 + 47981 = 47986
- 17 + 47969 = 47986
- 23 + 47963 = 47986
- 47 + 47939 = 47986
- 53 + 47933 = 47986
- 83 + 47903 = 47986
- 149 + 47837 = 47986
- 167 + 47819 = 47986
Showing the first eight; more decompositions exist.
