Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159972, here are decompositions:
- 41 + 159931 = 159972
- 61 + 159911 = 159972
- 73 + 159899 = 159972
- 101 + 159871 = 159972
- 103 + 159869 = 159972
- 139 + 159833 = 159972
- 173 + 159799 = 159972
- 179 + 159793 = 159972
Showing the first eight; more decompositions exist.
