Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9880, here are decompositions:
- 23 + 9857 = 9880
- 29 + 9851 = 9880
- 41 + 9839 = 9880
- 47 + 9833 = 9880
- 89 + 9791 = 9880
- 113 + 9767 = 9880
- 131 + 9749 = 9880
- 137 + 9743 = 9880
Showing the first eight; more decompositions exist.
