Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78864, here are decompositions:
- 7 + 78857 = 78864
- 11 + 78853 = 78864
- 41 + 78823 = 78864
- 61 + 78803 = 78864
- 67 + 78797 = 78864
- 73 + 78791 = 78864
- 83 + 78781 = 78864
- 127 + 78737 = 78864
Showing the first eight; more decompositions exist.
