Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33912, here are decompositions:
- 19 + 33893 = 33912
- 23 + 33889 = 33912
- 41 + 33871 = 33912
- 61 + 33851 = 33912
- 83 + 33829 = 33912
- 101 + 33811 = 33912
- 103 + 33809 = 33912
- 139 + 33773 = 33912
Showing the first eight; more decompositions exist.
