Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115828, here are decompositions:
- 5 + 115823 = 115828
- 17 + 115811 = 115828
- 47 + 115781 = 115828
- 59 + 115769 = 115828
- 71 + 115757 = 115828
- 101 + 115727 = 115828
- 149 + 115679 = 115828
- 191 + 115637 = 115828
Showing the first eight; more decompositions exist.
