Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5728, here are decompositions:
- 11 + 5717 = 5728
- 17 + 5711 = 5728
- 59 + 5669 = 5728
- 71 + 5657 = 5728
- 89 + 5639 = 5728
- 137 + 5591 = 5728
- 197 + 5531 = 5728
- 227 + 5501 = 5728
Showing the first eight; more decompositions exist.
