Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33640, here are decompositions:
- 3 + 33637 = 33640
- 11 + 33629 = 33640
- 17 + 33623 = 33640
- 23 + 33617 = 33640
- 41 + 33599 = 33640
- 53 + 33587 = 33640
- 59 + 33581 = 33640
- 71 + 33569 = 33640
Showing the first eight; more decompositions exist.
