Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47680, here are decompositions:
- 23 + 47657 = 47680
- 41 + 47639 = 47680
- 71 + 47609 = 47680
- 89 + 47591 = 47680
- 137 + 47543 = 47680
- 167 + 47513 = 47680
- 173 + 47507 = 47680
- 179 + 47501 = 47680
Showing the first eight; more decompositions exist.
