Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158878, here are decompositions:
- 11 + 158867 = 158878
- 29 + 158849 = 158878
- 101 + 158777 = 158878
- 107 + 158771 = 158878
- 131 + 158747 = 158878
- 179 + 158699 = 158878
- 257 + 158621 = 158878
- 281 + 158597 = 158878
Showing the first eight; more decompositions exist.
