Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115918, here are decompositions:
- 17 + 115901 = 115918
- 41 + 115877 = 115918
- 59 + 115859 = 115918
- 107 + 115811 = 115918
- 137 + 115781 = 115918
- 149 + 115769 = 115918
- 167 + 115751 = 115918
- 191 + 115727 = 115918
Showing the first eight; more decompositions exist.
