Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9814, here are decompositions:
- 3 + 9811 = 9814
- 11 + 9803 = 9814
- 23 + 9791 = 9814
- 47 + 9767 = 9814
- 71 + 9743 = 9814
- 137 + 9677 = 9814
- 191 + 9623 = 9814
- 227 + 9587 = 9814
Showing the first eight; more decompositions exist.
