Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43684, here are decompositions:
- 23 + 43661 = 43684
- 71 + 43613 = 43684
- 107 + 43577 = 43684
- 167 + 43517 = 43684
- 197 + 43487 = 43684
- 227 + 43457 = 43684
- 233 + 43451 = 43684
- 257 + 43427 = 43684
Showing the first eight; more decompositions exist.
