Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47988, here are decompositions:

7 + 47981 = 47988
11 + 47977 = 47988
19 + 47969 = 47988
37 + 47951 = 47988
41 + 47947 = 47988
71 + 47917 = 47988
107 + 47881 = 47988
131 + 47857 = 47988

Showing the first eight; more decompositions exist.
