Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9784, here are decompositions:
- 3 + 9781 = 9784
- 17 + 9767 = 9784
- 41 + 9743 = 9784
- 107 + 9677 = 9784
- 197 + 9587 = 9784
- 233 + 9551 = 9784
- 251 + 9533 = 9784
- 263 + 9521 = 9784
Showing the first eight; more decompositions exist.
