Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710218, here are decompositions:

5 + 8710213 = 8710218
71 + 8710147 = 8710218
109 + 8710109 = 8710218
157 + 8710061 = 8710218
197 + 8710021 = 8710218
227 + 8709991 = 8710218
239 + 8709979 = 8710218
277 + 8709941 = 8710218

Showing the first eight; more decompositions exist.
