Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115858, here are decompositions:
- 5 + 115853 = 115858
- 47 + 115811 = 115858
- 89 + 115769 = 115858
- 101 + 115757 = 115858
- 107 + 115751 = 115858
- 131 + 115727 = 115858
- 179 + 115679 = 115858
- 227 + 115631 = 115858
Showing the first eight; more decompositions exist.
