Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543996, here are decompositions:
- 5 + 31543991 = 31543996
- 17 + 31543979 = 31543996
- 83 + 31543913 = 31543996
- 89 + 31543907 = 31543996
- 137 + 31543859 = 31543996
- 149 + 31543847 = 31543996
- 167 + 31543829 = 31543996
- 179 + 31543817 = 31543996
Showing the first eight; more decompositions exist.
