Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52728, here are decompositions:
- 7 + 52721 = 52728
- 17 + 52711 = 52728
- 19 + 52709 = 52728
- 31 + 52697 = 52728
- 37 + 52691 = 52728
- 61 + 52667 = 52728
- 89 + 52639 = 52728
- 97 + 52631 = 52728
Showing the first eight; more decompositions exist.
