Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158938, here are decompositions:
- 11 + 158927 = 158938
- 29 + 158909 = 158938
- 71 + 158867 = 158938
- 89 + 158849 = 158938
- 167 + 158771 = 158938
- 179 + 158759 = 158938
- 191 + 158747 = 158938
- 239 + 158699 = 158938
Showing the first eight; more decompositions exist.
