Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6564, here are decompositions:
- 11 + 6553 = 6564
- 13 + 6551 = 6564
- 17 + 6547 = 6564
- 43 + 6521 = 6564
- 73 + 6491 = 6564
- 83 + 6481 = 6564
- 113 + 6451 = 6564
- 137 + 6427 = 6564
Showing the first eight; more decompositions exist.
