Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47994, here are decompositions:
- 13 + 47981 = 47994
- 17 + 47977 = 47994
- 31 + 47963 = 47994
- 43 + 47951 = 47994
- 47 + 47947 = 47994
- 61 + 47933 = 47994
- 83 + 47911 = 47994
- 113 + 47881 = 47994
Showing the first eight; more decompositions exist.
