Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47982, here are decompositions:
- 5 + 47977 = 47982
- 13 + 47969 = 47982
- 19 + 47963 = 47982
- 31 + 47951 = 47982
- 43 + 47939 = 47982
- 71 + 47911 = 47982
- 79 + 47903 = 47982
- 101 + 47881 = 47982
Showing the first eight; more decompositions exist.
