Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47988, here are decompositions:
- 7 + 47981 = 47988
- 11 + 47977 = 47988
- 19 + 47969 = 47988
- 37 + 47951 = 47988
- 41 + 47947 = 47988
- 71 + 47917 = 47988
- 107 + 47881 = 47988
- 131 + 47857 = 47988
Showing the first eight; more decompositions exist.
