Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33840, here are decompositions:
- 11 + 33829 = 33840
- 13 + 33827 = 33840
- 29 + 33811 = 33840
- 31 + 33809 = 33840
- 43 + 33797 = 33840
- 67 + 33773 = 33840
- 71 + 33769 = 33840
- 73 + 33767 = 33840
Showing the first eight; more decompositions exist.
