Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5646, here are decompositions:
- 5 + 5641 = 5646
- 7 + 5639 = 5646
- 23 + 5623 = 5646
- 73 + 5573 = 5646
- 83 + 5563 = 5646
- 89 + 5557 = 5646
- 127 + 5519 = 5646
- 139 + 5507 = 5646
Showing the first eight; more decompositions exist.
