Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43668, here are decompositions:
- 7 + 43661 = 43668
- 17 + 43651 = 43668
- 19 + 43649 = 43668
- 41 + 43627 = 43668
- 59 + 43609 = 43668
- 61 + 43607 = 43668
- 71 + 43597 = 43668
- 89 + 43579 = 43668
Showing the first eight; more decompositions exist.
