Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78880, here are decompositions:
- 3 + 78877 = 78880
- 23 + 78857 = 78880
- 41 + 78839 = 78880
- 71 + 78809 = 78880
- 83 + 78797 = 78880
- 89 + 78791 = 78880
- 101 + 78779 = 78880
- 167 + 78713 = 78880
Showing the first eight; more decompositions exist.
