Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115864, here are decompositions:
- 3 + 115861 = 115864
- 5 + 115859 = 115864
- 11 + 115853 = 115864
- 41 + 115823 = 115864
- 53 + 115811 = 115864
- 71 + 115793 = 115864
- 83 + 115781 = 115864
- 101 + 115763 = 115864
Showing the first eight; more decompositions exist.
