Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159940, here are decompositions:
- 3 + 159937 = 159940
- 29 + 159911 = 159940
- 41 + 159899 = 159940
- 71 + 159869 = 159940
- 83 + 159857 = 159940
- 101 + 159839 = 159940
- 107 + 159833 = 159940
- 149 + 159791 = 159940
Showing the first eight; more decompositions exist.
