Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706238, here are decompositions:

17 + 8706221 = 8706238
41 + 8706197 = 8706238
89 + 8706149 = 8706238
131 + 8706107 = 8706238
137 + 8706101 = 8706238
179 + 8706059 = 8706238
227 + 8706011 = 8706238
239 + 8705999 = 8706238

Showing the first eight; more decompositions exist.
