Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33920, here are decompositions:
- 31 + 33889 = 33920
- 109 + 33811 = 33920
- 151 + 33769 = 33920
- 163 + 33757 = 33920
- 181 + 33739 = 33920
- 199 + 33721 = 33920
- 241 + 33679 = 33920
- 283 + 33637 = 33920
Showing the first eight; more decompositions exist.
