Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706388, here are decompositions:

11 + 8706377 = 8706388
101 + 8706287 = 8706388
137 + 8706251 = 8706388
149 + 8706239 = 8706388
167 + 8706221 = 8706388
191 + 8706197 = 8706388
239 + 8706149 = 8706388
281 + 8706107 = 8706388

Showing the first eight; more decompositions exist.
