Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5566, here are decompositions:
- 3 + 5563 = 5566
- 47 + 5519 = 5566
- 59 + 5507 = 5566
- 83 + 5483 = 5566
- 89 + 5477 = 5566
- 149 + 5417 = 5566
- 167 + 5399 = 5566
- 173 + 5393 = 5566
Showing the first eight; more decompositions exist.
