Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47966, here are decompositions:
- 3 + 47963 = 47966
- 19 + 47947 = 47966
- 97 + 47869 = 47966
- 109 + 47857 = 47966
- 157 + 47809 = 47966
- 223 + 47743 = 47966
- 229 + 47737 = 47966
- 307 + 47659 = 47966
Showing the first eight; more decompositions exist.
