Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47986, here are decompositions:

5 + 47981 = 47986
17 + 47969 = 47986
23 + 47963 = 47986
47 + 47939 = 47986
53 + 47933 = 47986
83 + 47903 = 47986
149 + 47837 = 47986
167 + 47819 = 47986

Showing the first eight; more decompositions exist.
