Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5656, here are decompositions:
- 3 + 5653 = 5656
- 5 + 5651 = 5656
- 17 + 5639 = 5656
- 83 + 5573 = 5656
- 137 + 5519 = 5656
- 149 + 5507 = 5656
- 173 + 5483 = 5656
- 179 + 5477 = 5656
Showing the first eight; more decompositions exist.
