Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47980, here are decompositions:
- 3 + 47977 = 47980
- 11 + 47969 = 47980
- 17 + 47963 = 47980
- 29 + 47951 = 47980
- 41 + 47939 = 47980
- 47 + 47933 = 47980
- 137 + 47843 = 47980
- 173 + 47807 = 47980
Showing the first eight; more decompositions exist.
