Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29986, here are decompositions:
- 3 + 29983 = 29986
- 59 + 29927 = 29986
- 107 + 29879 = 29986
- 113 + 29873 = 29986
- 149 + 29837 = 29986
- 167 + 29819 = 29986
- 197 + 29789 = 29986
- 227 + 29759 = 29986
Showing the first eight; more decompositions exist.
