Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47680, here are decompositions:

23 + 47657 = 47680
41 + 47639 = 47680
71 + 47609 = 47680
89 + 47591 = 47680
137 + 47543 = 47680
167 + 47513 = 47680
173 + 47507 = 47680
179 + 47501 = 47680

Showing the first eight; more decompositions exist.
