Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47984, here are decompositions:
- 3 + 47981 = 47984
- 7 + 47977 = 47984
- 37 + 47947 = 47984
- 67 + 47917 = 47984
- 73 + 47911 = 47984
- 103 + 47881 = 47984
- 127 + 47857 = 47984
- 193 + 47791 = 47984
Showing the first eight; more decompositions exist.
