Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43866, here are decompositions:
- 13 + 43853 = 43866
- 73 + 43793 = 43866
- 79 + 43787 = 43866
- 83 + 43783 = 43866
- 89 + 43777 = 43866
- 107 + 43759 = 43866
- 113 + 43753 = 43866
- 149 + 43717 = 43866
Showing the first eight; more decompositions exist.
