Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30882, here are decompositions:
- 11 + 30871 = 30882
- 13 + 30869 = 30882
- 23 + 30859 = 30882
- 29 + 30853 = 30882
- 31 + 30851 = 30882
- 41 + 30841 = 30882
- 43 + 30839 = 30882
- 53 + 30829 = 30882
Showing the first eight; more decompositions exist.
