Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78966, here are decompositions:
- 37 + 78929 = 78966
- 47 + 78919 = 78966
- 73 + 78893 = 78966
- 79 + 78887 = 78966
- 89 + 78877 = 78966
- 109 + 78857 = 78966
- 113 + 78853 = 78966
- 127 + 78839 = 78966
Showing the first eight; more decompositions exist.
