Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4564, here are decompositions:
- 3 + 4561 = 4564
- 17 + 4547 = 4564
- 41 + 4523 = 4564
- 47 + 4517 = 4564
- 71 + 4493 = 4564
- 83 + 4481 = 4564
- 101 + 4463 = 4564
- 107 + 4457 = 4564
Showing the first eight; more decompositions exist.
