Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33880, here are decompositions:
- 17 + 33863 = 33880
- 23 + 33857 = 33880
- 29 + 33851 = 33880
- 53 + 33827 = 33880
- 71 + 33809 = 33880
- 83 + 33797 = 33880
- 89 + 33791 = 33880
- 107 + 33773 = 33880
Showing the first eight; more decompositions exist.
