Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647366, here are decompositions:

17 + 8647349 = 8647366
89 + 8647277 = 8647366
113 + 8647253 = 8647366
137 + 8647229 = 8647366
173 + 8647193 = 8647366
227 + 8647139 = 8647366
239 + 8647127 = 8647366
359 + 8647007 = 8647366

Showing the first eight; more decompositions exist.
