Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647426, here are decompositions:

17 + 8647409 = 8647426
59 + 8647367 = 8647426
149 + 8647277 = 8647426
173 + 8647253 = 8647426
197 + 8647229 = 8647426
233 + 8647193 = 8647426
269 + 8647157 = 8647426
383 + 8647043 = 8647426

Showing the first eight; more decompositions exist.
