Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31968, here are decompositions:
- 5 + 31963 = 31968
- 11 + 31957 = 31968
- 61 + 31907 = 31968
- 109 + 31859 = 31968
- 151 + 31817 = 31968
- 197 + 31771 = 31968
- 199 + 31769 = 31968
- 227 + 31741 = 31968
Showing the first eight; more decompositions exist.
