Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158860, here are decompositions:
- 11 + 158849 = 158860
- 17 + 158843 = 158860
- 83 + 158777 = 158860
- 89 + 158771 = 158860
- 101 + 158759 = 158860
- 113 + 158747 = 158860
- 197 + 158663 = 158860
- 227 + 158633 = 158860
Showing the first eight; more decompositions exist.
