Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47976, here are decompositions:
- 7 + 47969 = 47976
- 13 + 47963 = 47976
- 29 + 47947 = 47976
- 37 + 47939 = 47976
- 43 + 47933 = 47976
- 59 + 47917 = 47976
- 73 + 47903 = 47976
- 107 + 47869 = 47976
Showing the first eight; more decompositions exist.
