Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31644, here are decompositions:
- 17 + 31627 = 31644
- 37 + 31607 = 31644
- 43 + 31601 = 31644
- 61 + 31583 = 31644
- 71 + 31573 = 31644
- 97 + 31547 = 31644
- 101 + 31543 = 31644
- 103 + 31541 = 31644
Showing the first eight; more decompositions exist.
