Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78960, here are decompositions:
- 19 + 78941 = 78960
- 31 + 78929 = 78960
- 41 + 78919 = 78960
- 59 + 78901 = 78960
- 67 + 78893 = 78960
- 71 + 78889 = 78960
- 73 + 78887 = 78960
- 83 + 78877 = 78960
Showing the first eight; more decompositions exist.
