Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47998, here are decompositions:
- 17 + 47981 = 47998
- 29 + 47969 = 47998
- 47 + 47951 = 47998
- 59 + 47939 = 47998
- 179 + 47819 = 47998
- 191 + 47807 = 47998
- 257 + 47741 = 47998
- 281 + 47717 = 47998
Showing the first eight; more decompositions exist.
