Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143566, here are decompositions:
- 29 + 143537 = 143566
- 47 + 143519 = 143566
- 53 + 143513 = 143566
- 83 + 143483 = 143566
- 89 + 143477 = 143566
- 179 + 143387 = 143566
- 233 + 143333 = 143566
- 317 + 143249 = 143566
Showing the first eight; more decompositions exist.
