Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656216, here are decompositions:

47 + 8656169 = 8656216
53 + 8656163 = 8656216
83 + 8656133 = 8656216
137 + 8656079 = 8656216
197 + 8656019 = 8656216
263 + 8655953 = 8656216
293 + 8655923 = 8656216
347 + 8655869 = 8656216

Showing the first eight; more decompositions exist.
