Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158752, here are decompositions:
- 3 + 158749 = 158752
- 5 + 158747 = 158752
- 53 + 158699 = 158752
- 89 + 158663 = 158752
- 131 + 158621 = 158752
- 179 + 158573 = 158752
- 233 + 158519 = 158752
- 263 + 158489 = 158752
Showing the first eight; more decompositions exist.
