Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9912, here are decompositions:
- 5 + 9907 = 9912
- 11 + 9901 = 9912
- 29 + 9883 = 9912
- 41 + 9871 = 9912
- 53 + 9859 = 9912
- 61 + 9851 = 9912
- 73 + 9839 = 9912
- 79 + 9833 = 9912
Showing the first eight; more decompositions exist.
