Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79858, here are decompositions:
- 11 + 79847 = 79858
- 17 + 79841 = 79858
- 29 + 79829 = 79858
- 41 + 79817 = 79858
- 47 + 79811 = 79858
- 89 + 79769 = 79858
- 101 + 79757 = 79858
- 167 + 79691 = 79858
Showing the first eight; more decompositions exist.
