Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43644, here are decompositions:
- 11 + 43633 = 43644
- 17 + 43627 = 43644
- 31 + 43613 = 43644
- 37 + 43607 = 43644
- 47 + 43597 = 43644
- 53 + 43591 = 43644
- 67 + 43577 = 43644
- 71 + 43573 = 43644
Showing the first eight; more decompositions exist.
