Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3912, here are decompositions:
- 5 + 3907 = 3912
- 23 + 3889 = 3912
- 31 + 3881 = 3912
- 59 + 3853 = 3912
- 61 + 3851 = 3912
- 79 + 3833 = 3912
- 89 + 3823 = 3912
- 109 + 3803 = 3912
Showing the first eight; more decompositions exist.
