Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65890, here are decompositions:
- 23 + 65867 = 65890
- 47 + 65843 = 65890
- 53 + 65837 = 65890
- 59 + 65831 = 65890
- 101 + 65789 = 65890
- 113 + 65777 = 65890
- 173 + 65717 = 65890
- 191 + 65699 = 65890
Showing the first eight; more decompositions exist.
