Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47728, here are decompositions:
- 11 + 47717 = 47728
- 17 + 47711 = 47728
- 29 + 47699 = 47728
- 47 + 47681 = 47728
- 71 + 47657 = 47728
- 89 + 47639 = 47728
- 137 + 47591 = 47728
- 227 + 47501 = 47728
Showing the first eight; more decompositions exist.
