Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158660, here are decompositions:
- 3 + 158657 = 158660
- 13 + 158647 = 158660
- 43 + 158617 = 158660
- 79 + 158581 = 158660
- 97 + 158563 = 158660
- 109 + 158551 = 158660
- 211 + 158449 = 158660
- 241 + 158419 = 158660
Showing the first eight; more decompositions exist.
