Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47218, here are decompositions:

11 + 47207 = 47218
29 + 47189 = 47218
71 + 47147 = 47218
89 + 47129 = 47218
107 + 47111 = 47218
131 + 47087 = 47218
167 + 47051 = 47218
317 + 46901 = 47218

Showing the first eight; more decompositions exist.
