Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19764, here are decompositions:
- 5 + 19759 = 19764
- 11 + 19753 = 19764
- 13 + 19751 = 19764
- 37 + 19727 = 19764
- 47 + 19717 = 19764
- 67 + 19697 = 19764
- 83 + 19681 = 19764
- 103 + 19661 = 19764
Showing the first eight; more decompositions exist.
