Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43666, here are decompositions:
- 5 + 43661 = 43666
- 17 + 43649 = 43666
- 53 + 43613 = 43666
- 59 + 43607 = 43666
- 89 + 43577 = 43666
- 149 + 43517 = 43666
- 167 + 43499 = 43666
- 179 + 43487 = 43666
Showing the first eight; more decompositions exist.
