Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27970, here are decompositions:
- 3 + 27967 = 27970
- 17 + 27953 = 27970
- 23 + 27947 = 27970
- 29 + 27941 = 27970
- 53 + 27917 = 27970
- 167 + 27803 = 27970
- 179 + 27791 = 27970
- 191 + 27779 = 27970
Showing the first eight; more decompositions exist.
