Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4566, here are decompositions:
- 5 + 4561 = 4566
- 17 + 4549 = 4566
- 19 + 4547 = 4566
- 43 + 4523 = 4566
- 47 + 4519 = 4566
- 53 + 4513 = 4566
- 59 + 4507 = 4566
- 73 + 4493 = 4566
Showing the first eight; more decompositions exist.
