Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43784, here are decompositions:
- 3 + 43781 = 43784
- 7 + 43777 = 43784
- 31 + 43753 = 43784
- 67 + 43717 = 43784
- 73 + 43711 = 43784
- 151 + 43633 = 43784
- 157 + 43627 = 43784
- 193 + 43591 = 43784
Showing the first eight; more decompositions exist.
