Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47686, here are decompositions:
- 5 + 47681 = 47686
- 29 + 47657 = 47686
- 47 + 47639 = 47686
- 173 + 47513 = 47686
- 179 + 47507 = 47686
- 227 + 47459 = 47686
- 269 + 47417 = 47686
- 347 + 47339 = 47686
Showing the first eight; more decompositions exist.
