Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40564, here are decompositions:
- 5 + 40559 = 40564
- 71 + 40493 = 40564
- 131 + 40433 = 40564
- 137 + 40427 = 40564
- 281 + 40283 = 40564
- 311 + 40253 = 40564
- 401 + 40163 = 40564
- 593 + 39971 = 40564
Showing the first eight; more decompositions exist.
