Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656824, here are decompositions:

17 + 8656807 = 8656824
23 + 8656801 = 8656824
37 + 8656787 = 8656824
97 + 8656727 = 8656824
103 + 8656721 = 8656824
157 + 8656667 = 8656824
251 + 8656573 = 8656824
263 + 8656561 = 8656824

Showing the first eight; more decompositions exist.
