Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656338, here are decompositions:

17 + 8656321 = 8656338
59 + 8656279 = 8656338
107 + 8656231 = 8656338
149 + 8656189 = 8656338
167 + 8656171 = 8656338
179 + 8656159 = 8656338
191 + 8656147 = 8656338
241 + 8656097 = 8656338

Showing the first eight; more decompositions exist.
