Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3566, here are decompositions:
- 7 + 3559 = 3566
- 19 + 3547 = 3566
- 37 + 3529 = 3566
- 67 + 3499 = 3566
- 97 + 3469 = 3566
- 103 + 3463 = 3566
- 109 + 3457 = 3566
- 193 + 3373 = 3566
Showing the first eight; more decompositions exist.
