Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43564, here are decompositions:
- 23 + 43541 = 43564
- 47 + 43517 = 43564
- 83 + 43481 = 43564
- 107 + 43457 = 43564
- 113 + 43451 = 43564
- 137 + 43427 = 43564
- 167 + 43397 = 43564
- 173 + 43391 = 43564
Showing the first eight; more decompositions exist.
