Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47278, here are decompositions:

41 + 47237 = 47278
71 + 47207 = 47278
89 + 47189 = 47278
131 + 47147 = 47278
149 + 47129 = 47278
167 + 47111 = 47278
191 + 47087 = 47278
227 + 47051 = 47278

Showing the first eight; more decompositions exist.
