Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158758, here are decompositions:
- 11 + 158747 = 158758
- 59 + 158699 = 158758
- 101 + 158657 = 158758
- 137 + 158621 = 158758
- 167 + 158591 = 158758
- 191 + 158567 = 158758
- 239 + 158519 = 158758
- 251 + 158507 = 158758
Showing the first eight; more decompositions exist.
