Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19656, here are decompositions:
- 47 + 19609 = 19656
- 53 + 19603 = 19656
- 59 + 19597 = 19656
- 73 + 19583 = 19656
- 79 + 19577 = 19656
- 97 + 19559 = 19656
- 103 + 19553 = 19656
- 113 + 19543 = 19656
Showing the first eight; more decompositions exist.
