Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19704, here are decompositions:
- 5 + 19699 = 19704
- 7 + 19697 = 19704
- 17 + 19687 = 19704
- 23 + 19681 = 19704
- 43 + 19661 = 19704
- 101 + 19603 = 19704
- 107 + 19597 = 19704
- 127 + 19577 = 19704
Showing the first eight; more decompositions exist.
