Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115668, here are decompositions:
- 5 + 115663 = 115668
- 11 + 115657 = 115668
- 31 + 115637 = 115668
- 37 + 115631 = 115668
- 67 + 115601 = 115668
- 71 + 115597 = 115668
- 79 + 115589 = 115668
- 97 + 115571 = 115668
Showing the first eight; more decompositions exist.
