Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71218, here are decompositions:

47 + 71171 = 71218
71 + 71147 = 71218
89 + 71129 = 71218
137 + 71081 = 71218
149 + 71069 = 71218
179 + 71039 = 71218
227 + 70991 = 71218
239 + 70979 = 71218

Showing the first eight; more decompositions exist.
