Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9864, here are decompositions:
- 5 + 9859 = 9864
- 7 + 9857 = 9864
- 13 + 9851 = 9864
- 31 + 9833 = 9864
- 47 + 9817 = 9864
- 53 + 9811 = 9864
- 61 + 9803 = 9864
- 73 + 9791 = 9864
Showing the first eight; more decompositions exist.
