Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656864, here are decompositions:

17 + 8656847 = 8656864
131 + 8656733 = 8656864
137 + 8656727 = 8656864
173 + 8656691 = 8656864
197 + 8656667 = 8656864
317 + 8656547 = 8656864
347 + 8656517 = 8656864
353 + 8656511 = 8656864

Showing the first eight; more decompositions exist.
