Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33642, here are decompositions:
- 5 + 33637 = 33642
- 13 + 33629 = 33642
- 19 + 33623 = 33642
- 23 + 33619 = 33642
- 29 + 33613 = 33642
- 41 + 33601 = 33642
- 43 + 33599 = 33642
- 53 + 33589 = 33642
Showing the first eight; more decompositions exist.
