Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706886, here are decompositions:

5 + 8706881 = 8706886
17 + 8706869 = 8706886
53 + 8706833 = 8706886
179 + 8706707 = 8706886
239 + 8706647 = 8706886
317 + 8706569 = 8706886
359 + 8706527 = 8706886
389 + 8706497 = 8706886

Showing the first eight; more decompositions exist.
