Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656884, here are decompositions:

13 + 8656871 = 8656884
37 + 8656847 = 8656884
53 + 8656831 = 8656884
83 + 8656801 = 8656884
97 + 8656787 = 8656884
151 + 8656733 = 8656884
157 + 8656727 = 8656884
163 + 8656721 = 8656884

Showing the first eight; more decompositions exist.
