Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115818, here are decompositions:
- 7 + 115811 = 115818
- 11 + 115807 = 115818
- 37 + 115781 = 115818
- 41 + 115777 = 115818
- 47 + 115771 = 115818
- 61 + 115757 = 115818
- 67 + 115751 = 115818
- 139 + 115679 = 115818
Showing the first eight; more decompositions exist.
