Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78988, here are decompositions:
- 11 + 78977 = 78988
- 47 + 78941 = 78988
- 59 + 78929 = 78988
- 101 + 78887 = 78988
- 131 + 78857 = 78988
- 149 + 78839 = 78988
- 179 + 78809 = 78988
- 191 + 78797 = 78988
Showing the first eight; more decompositions exist.
