Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47686, here are decompositions:

5 + 47681 = 47686
29 + 47657 = 47686
47 + 47639 = 47686
173 + 47513 = 47686
179 + 47507 = 47686
227 + 47459 = 47686
269 + 47417 = 47686
347 + 47339 = 47686

Showing the first eight; more decompositions exist.
