Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9906, here are decompositions:
- 5 + 9901 = 9906
- 19 + 9887 = 9906
- 23 + 9883 = 9906
- 47 + 9859 = 9906
- 67 + 9839 = 9906
- 73 + 9833 = 9906
- 89 + 9817 = 9906
- 103 + 9803 = 9906
Showing the first eight; more decompositions exist.
