Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158928, here are decompositions:
- 5 + 158923 = 158928
- 19 + 158909 = 158928
- 47 + 158881 = 158928
- 61 + 158867 = 158928
- 79 + 158849 = 158928
- 137 + 158791 = 158928
- 151 + 158777 = 158928
- 157 + 158771 = 158928
Showing the first eight; more decompositions exist.
