Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47980, here are decompositions:

3 + 47977 = 47980
11 + 47969 = 47980
17 + 47963 = 47980
29 + 47951 = 47980
41 + 47939 = 47980
47 + 47933 = 47980
137 + 47843 = 47980
173 + 47807 = 47980

Showing the first eight; more decompositions exist.
