Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78970, here are decompositions:
- 29 + 78941 = 78970
- 41 + 78929 = 78970
- 83 + 78887 = 78970
- 113 + 78857 = 78970
- 131 + 78839 = 78970
- 167 + 78803 = 78970
- 173 + 78797 = 78970
- 179 + 78791 = 78970
Showing the first eight; more decompositions exist.
