Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33780, here are decompositions:
- 7 + 33773 = 33780
- 11 + 33769 = 33780
- 13 + 33767 = 33780
- 23 + 33757 = 33780
- 29 + 33751 = 33780
- 31 + 33749 = 33780
- 41 + 33739 = 33780
- 59 + 33721 = 33780
Showing the first eight; more decompositions exist.
