Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33930, here are decompositions:
- 7 + 33923 = 33930
- 19 + 33911 = 33930
- 37 + 33893 = 33930
- 41 + 33889 = 33930
- 59 + 33871 = 33930
- 67 + 33863 = 33930
- 73 + 33857 = 33930
- 79 + 33851 = 33930
Showing the first eight; more decompositions exist.
