Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43800, here are decompositions:
- 7 + 43793 = 43800
- 11 + 43789 = 43800
- 13 + 43787 = 43800
- 17 + 43783 = 43800
- 19 + 43781 = 43800
- 23 + 43777 = 43800
- 41 + 43759 = 43800
- 47 + 43753 = 43800
Showing the first eight; more decompositions exist.
