Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56566, here are decompositions:
- 23 + 56543 = 56566
- 47 + 56519 = 56566
- 89 + 56477 = 56566
- 113 + 56453 = 56566
- 149 + 56417 = 56566
- 173 + 56393 = 56566
- 197 + 56369 = 56566
- 233 + 56333 = 56566
Showing the first eight; more decompositions exist.
